Cryptocoryne Sp. Affinis Aka Cryptocoryne Sp. Haerteliana SUBMERSED Spathe Update

Upon noticing this plant flowering in submersed conditions, I begun taking weekly photo’s and watched the spathe daily to record it’s growth. Roughly speaking; the plant grew 0.75 inches a day (3/4 inch) on the slowest day, and 1.5 inches on it’s fastest day.

Since the plant is in an aquarium that is 22 inches tall, I didn’t imagine the spathe would be able to reach the surface since I’ve never seen another spathe this large throughout my research; however upon doing my daily check up on the aquarium yesterday, I noticed the spathe finally reached the surface. The only downfall is I also noticed the spathe was beginning to partially melt where it had broken the surface, so I decided to immediately cut it down to document the spathe and take some closer pictures.

After measuring the spathe it came in at a whopping 17+ inches !! to understand the sheer scale of the spathe, I took a video with the spathe against my arm, in which it reached from my elbow to wrist; I will post the video in a few days once edited.

Enjoy the pictures below!

Cryptocoryne Sp. Affinis AKA Cryptocoryne Sp. Haerteliana SUBMERSED Spathe

Rarely do Cryptocoryne’s flower fully submersed, but when they do you commonly hear it happening with something easy like a Wendtii species; to wake up and see that my Cryptocoryne Sp. Affinis was sending up a spathe SUBMERSED made me jump for joy.

There are only two known photo’s of a fully submersed Cryptocoryne Sp. Affinis spathe, and only one of the two is an actual real submersed spathe. The reason I say this is the second spathe is going out of the water since the plant is only submersed in a few inches of water; I attached both known photo’s below for all to see:

Photo 1 True Submersed –
Photo 2 Not Truly Submersed –

Even in the emersed state Cryptocoryne Sp. Affinis is not easy to flower, nor cultivate, which is why most international plant nurseries have stayed away from this plant OR can only offer it at certain times of the year. This makes this submersed spathe all the more special (in my opinion), especially since the plant is in a tank that is 22 inches tall.

The spathe is probably not fully developed yet but I don’t imagine it will get much larger then the pictures below as my research shows the spathe’s to commonly stay between 30-40cm.

The pictures are in order from when I first saw the spathe (3 days ago, Dec 9th) to now (Dec 12th):

I recently started dosing fertilizers in this tank on a more regular basis, as well as I removed the shade cloth and increased CO2, I’m not sure if this has anything to do with the plant sending up the spathe but it only started to develop after increasing light/ferts/co2.

As always here are the specs of the tank:

Lighting – Marineland Aquatic Plant LED 
Filtration – Marineland C220
CO2 – 2 BPS
Fertilization – Micro + Macro alternate days
Substrate – FAKE Plastic Gravel (Surprising eh?)

Cryptocoryne Cordata Var. Siamensis ‘Rosanervig’ Submersed

Cryptocoryne Cordata Var. Siamensis ‘Rosanervig’ is a very rare yet controversial plant due to it’s white/pink veining that no one has been able to put a thumb on. We do know that the veining is due to a virus, however the veining seems to either be very pronounced or not pronounced at all depending upon the set up they are in.

I have seen this species under high light conditions (60+ PAR) with it’s veining still present and very deep, while also seeing this species in another set up with med/high light where hardly any veining is pronounced.

For me personally I have only been able to get deep/rich white/pink veining to display under lower light conditions like you’ll see with this runner hidden behind a piece of driftwood…

IMG_1804 IMG_1805

HOWEVER; I also have a runner in the front of my tank where the light is MUCH brighter (60+ PAR) and you can clearly see a pronounced pink/white vein, although it is not as “thick” as the one hidden behind the driftwood.
IMG_1795 IMG_1794

This is a new leaf forming off the mother plant, the mother unfortunately does not have the greatest veining but the plant is an absolute monster at almost 18+ inches tall and constantly sending 10-15 runners every 6-8 months.
IMG_1798 IMG_1799 IMG_1800

Here are more runners, in total I have six runners currently popping up, all ranging in size from tiny plants just forming to daughters that have 2-3 leaves.

Cryptocoryne Wendtii Sp. ‘Green Gecko’

Since I’m in the process of tearing down tanks before I move, I sadly had to take down one of my tanks which houses a huge Cryptocoryne Wendtii Sp. ‘Green Gecko’ that has flowered submersed for me many times. The pictures you’ll see below include THREE spathes on ONE plant, yes that’s right three spathes on a single plant!!! This clearly shows how a nutrient rich substrate like the mineralized top soil that I use in all my submersed planted tanks really does give plants the extra boost they need as if they were in the wild. You rarely see Cryptocoryne’s flower submersed and when you do it’s generally 1 spathe, not 3; making this plant all that more special (in my eyes anyway).

I’ve been keeping this plant in a mineralized top soil substrate as previously mentioned, with a border of Seachem Flourite Dark and black sand as the cap. The PH stays roughly between 6.5 and 7.6, this does swing when I do water changes or when I don’t keep up on using Almond Leaves enough to lower the PH; now that I have a PH pen I can monitor this much better in my other tanks that are still up and running.

The tank itself is a simple 10 gallon tank with hood containing two 6700k 23 watt CFL bulbs, I do not use CO2 in this tank and I also do not dose any fertilizers; all the nutrients have come from the substrate itself and fish waste.

Fauna consists of: 15 fancy tail guppy fry and three ‘Super Red’ Bristlenose Ancistrus Plecostomus

Here are some pictures below that I took before I sold this plant to a friend of mine

Cryptocoryne Cf. Affinis

I originally purchased this plant as Cryptocoryne Cf. Affinis and to my understanding the .Cf is used when the species is undefined/unknown. I’ve had this plant growing in emersed conditions ever since I got it and it’s displayed a wide variety of colours for me in the time I’ve had it as you’ll see in the pictures below.

I hope one day this plant will send up a spathe so I can hopefully ID it but it’s still gorgeous nevertheless

As always here are the conditions in which it’s kept

Lighting- Coralife T5NO Dual Bulb – 6700k and rosette bulb – Lights are on for 10 hours. 
PH- 7.5
Substrate- Homemade substrate mix, cow manure, sheep manure, worm castings, natural red clay, and cheap topsoil.

Cryptocoryne Wendtii ‘Mi Oya’ Spathe Update 6

This plant has been consistently producing spathes for literally almost 3 months straight now; it’s almost as if it is begging to be pollinated. I decided to cut this one open in order to get a shot of the inside kettle and limb.

If you look closely you will notice a spathe on the left that I’ve cut open and a spathe on the right which is forming; as I’ve said this plant is CONSTANTLY sending up spathe’s for me.


Cryptocoryne Wendtii Sp. ‘Green Gecko’

I was cleaning my tank today and shot a nice picture of my Cryptocoryne Wendtii ‘Green Gecko’ which is submersed unlike many of the other Cryptocoryne’s I keep. I’ve actually had this plant send up spathe’s three times now in submersed conditions but I’ve never been able to get a good picture of it besides the previous posts in which I’ve shown the submersed spathe.

This plant has been in the same place for roughly 1 year now and is growing absolutely beautifully; below are also the conditions it’s in.

Lighting – X 2 Spiral CFL 6700K bulbs on for 10 hours a day
PH – 7.5 water changes done with R.O.D.I water
Temperature – 21-23 celsius – 69.8-73.4 fahrenheit
Fauna – X 3 Super Red Longfin Bristlenose Pleco’s
Substrate- Seachem Dark with Mineralized Top Soil underneath and black sand as a cap.


Cryptocoryne X Purpurea Ridley Nothovar. Purpurea ‘Kota Tingga’

This is by far probably the rarest Cryptocoryne I own, especially considering they have completely destroyed it’s natural habitat due to palm oil plantations being put up.  I really hope I can grow this one and propagate it so it can be spread to fellow hobbyists; here is a link for further information and pictures of the plant :

Since I literally just got this plant it still needs to adjust to it’s new conditions, I’ll be keeping it in my emersed tank like many other Cryptocoryne’s I own.

Lighting- Coralife T5NO Dual Bulb – 6700k and rosette bulb – Lights are on for 10 hours. 
PH- 7.5
Substrate- Homemade substrate mix, cow manure, sheep manure, worm castings, natural red clay, and cheap topsoil.

Cryptocoryne Cordata Var. Siamensis ‘Thailand Sungai Kolok CTSK’

There is little to no information on this Cryptocoryne anywhere on the internet; I can only trace it back to two people, one in which I know personally and is a great friend of mine; where the other one who originally brought this plant in hasn’t said much about it (at least from what I could find).

I just recently got this species on the weekend so it is still adapting to it’s new conditions and is quite small; however as it grows I will take lots of pictures.

Also, here is a link to my friend who posted a picture of the spathe when he had it blooming: Photo belongs to orchidnutz;Jim. R

Right now I have it under the following conditions:

Lighting- Coralife T5NO Dual Bulb – 6700k and rosette bulb – Lights are on for 10 hours. 
PH- 7.5
Substrate- Homemade substrate mix, cow manure, sheep manure, worm castings, natural red clay, and cheap topsoil.

Cryptocoryne Cordata Var. Siamensis ‘Blassii’

Cryptocoryne Cordata Var. Siamensis ‘Blassii’ is another plant that gave me trouble submersed, however in emersed conditions this plant grows extremely well and sends many daughter plants.

This is a great beginner Cryptocoryne that you don’t always see for sale; I originally got this species from Oriental Aquarium in Singapore.

Lighting- Coralife T5NO Dual Bulb – 6700k and rosette bulb – Lights are on for 10 hours. 
PH- 7.5
Substrate- Homemade substrate mix, cow manure, sheep manure, worm castings, natural red clay, and cheap topsoil.

In some pictures you can see the pink “shine” the plant has, it’s quite attractive.
