just out of curiousity, what size tank is that???

How amazing to see all those beautiful gastromyzons grazing at the algae party. I have, from time to time, grown algae on rocks for my hillstreams. When I put them in the tanks, the gastromyzons, psuedogastromyzons, and liniparhomaloptera go crazy. The freshly grown algae, and whatever else is growing of the rocks must be quite a treat.
If you plan on growing algae on rocks, I swould suggest using an air pump to add oxygen. It seems to make the algae grow quicker.
Keep those great pictures coming!!!

I once put in a batch of smooth pebbles covered in algae in my river tank, and the next thing I knew they were being attacked by the "punctulatus" although I am now in doubt if thats what they are.
Have we established a correct ID for the fish pictured in Martin's photos?

While this isn't set in stone, it is probably going to turn out that what we have been calling punctalatus, is actually ctenocephalus, and what we have been calling by that name is actually oscellatus.
Stay tuned for more developments.

Mike, if that's the same tank of Hendra's, it's 75X40X35 cm.

Thanks for comments.
Jim, thanks for the suggestion, I will add air from air pump to grow the algae on rocks!!
About the size of the tanks,

Wow! Lovely photos of the 'algae party' and of your chocolate gouramis, Hendra!
Can I ask you what the pH and hardness is of the water in your tanks? Also, would you know what the pH and hardness of the water in a typical Kalimantan river would be? If you have any information on this I would be really interested.

The parameter of water in streams or rivers in Kalimantan, I think, not so different with another region in South East Asia or another tropical area.
The pH value and hardness of water is depending on what type and the environment surround of stream/river.
For blackwater stream, the water can be very acidic without or very little hardness, pH value can reach below 4 especially in dry season. I just can say the ph value for black water is 4 – 6, temperature 24 – 28 Celcius, hardness (GH, KH) below 1 dh.
For freshwater hillstream, the water can very hard in limestone or karst area.
PH value is 6 – 8.5, GH from below 2 – 9, KH from below 2 – 11. Temperature 25 Celcius (average).
All data above is base on my friend’s data about water parameter from many location of stream.
About my tank’s water condition,
90 x 45 x 40, pH = 7,8 , TDS = 93 ppm, GH and KH < 2 dh, WT = 24.5 – 27 Celcius
80 x 45 x 40, pH = 7,7 , TDS = 77 ppm, GH and KH < 2 dh, WT = 25 - 27,5 Celcius
Hope this can help.

Thank you very much for the information, Hendra! I appreciate you taking the time to reply.
I had kind of guessed that some of the blackwater areas in Kalimantan would be very soft and acidic. Our Clown Loaches have been thriving for some time in soft water with a pH of around 5.

Your welcome Emma
I'm not really sure about the pH value for Clown in wild but I think 5 is good enough for blackwater species. If I don't wrong remember Bagrus dude ever showed picture of clown habitat in old forum.

Emma, you should check out this thread:
......if you want to see acid conditions. Nonn's description is pretty graphic.
Also there's a link to one of his awesome underwater movies shot in this bog. Plus .....(because it's Nonn) some mind-blowing photos.

Nice link, Graeme!
Agree with Martin, Nonn (and friends) always have high quality pics of fishes and their habitat.
Enclose another pic of Gastromyzon sp.
SW01, have nice iridescent blue color in middle of caudal fin.
