Some Gastromyzon pics.
In this tank are G. scitulus, G. ctenocephalus, G. viriosus and some of the G. ridens complex (probably G. zebrinus and/or G. stellatus).

Very nice!!
How many G. viriosus do you have?
I have never known anyone to post on this site that had more than one or two.
If only I could find some around here!

How many G. viriosus do you have?
I've got five of them.
They were all labeled as G. punctulatus.
It was the first time I spotted the viriosus overhere and couldn't resist taking some home. :)

A few months later.

Hillstream1
(Gastromyzon viriosus(7), G. zebrinus(7), G. ctenocephalus(1), Hypergastromyzon humilis(5), Sinogastromyzon puliensis(3), Rhinogobius duospilus(5) and Tanichthys albonubes)
Probably the species from Borneo will get their own tank.

I had forgotten about this thread.
The dark colored zebrinus like fish are very similar to the mystery gastromyson I found a few weeks ago. I wonder if they are a local variation of Gastromyzon zebrinus or another of the ridens group?
My fish, like these, is much darker with fainter markings, than the other zebrinus I have.

Most of the ten G. zebrinus I've got can be very dark.
The 3 biggest ones (around 6 cm TL) have somewhat fainter markings that almost completely disappear when they have a territorial dispute.

But they can also be lightbrown, darkgreen, darkbrown etc.. It depends on the surface they're on.
I've got only one that's a bit different; It's always chocolate brown and has different markings in the caudal fin.

Some pics of the biggest G. zebrinus (6.2 cm TL,5.2 SL)
It's the same as the right one in the first picture of this thread.

And the chocolate brown one.

Again, and a zebrinus with a 'normal' caudal on the right.
The chocolate brown one has only some faint blue at the tip of the caudal.

Looking at Dr. Tan's book, no mention of red in the caudal fin of g. zebrinas. The head markings aren't right either, look more like g. crenastus which can have red in the caudal. ??????

Aha you finally got a copy Jim! :D I had a look through the book when Henri originally posted this fish and couldn't match it to any of the described species. Dr. Tan doesn't mention red in the caudal of G. zebrinus but neither blue in the dorsal of G. scitulus which some specimens do have so maybe these features vary with population?

Ps. Henri your tanks look great!

Yeah Matt, finally! I ordered from Singapore and it got lost in the mail for 2 months. I thought it was lost for good and then just showed up one day, great book!
Soooo many variations. If I had another lifetime I'd move to Bormeo and study these down to the genetics!

Beautiful tanks and fish you have there! Do you grow the algae on the rocks yourself or is it just by accident?

Yeah, I am interested in knowing how you have grown the algae on the rocks as well.
5ft long rocky hillstream tank - Sewellia lineolata and spotted... and lots (and lots) of spotted fry
8ft Clown loach tank: 30+ clown loaches, 10+ Yoyos.
6ft tank for 16x botia kubotai, 13x Striata, 6x Sidthimunki - I need more sids
