Gastromyzon ID - mixed bag
Hello- I've had these for going on two weeks now and have had a great time trying to identify the (4 or 5) species. Any input would be appreciated. I'm thinking the topmost is g. Viriosus and I'm pretty sure the bottom right is hypergastromyzon humilis. The one I'm really curious about is the second from the top with the reticulated markings. I believe the remaining three are g. Zebrinus or at least the two darker ones are. I have lots more pics if that would help. Unfortunately, I don't have any specific collection data other than Borneo. Thanks for looking!

Re: Gastromyzon ID - mixed bag
That's a very nice mix of hillstreams! I'm jealous!
I would agree with all your IDs.
As for the reticulated one (and possibly the light colored fish directly below it), they could possibly be cranbrooki, but I am not by any means positive.
I have seen pictures of gastros like this lately on other websites and there seems to be some question as to what they are.
More pictures might help clarify things.

Re: Gastromyzon ID - mixed bag
Thanks, Jim! These originally came in a group of 12 and after receiving this group I caved and bought the other 6. So now I have at least two of each. Looking at the full complement I'm convinced the lighter "zebrinus" is a different species or variant. Here are a few more pictures of both the reticulated and the lighter one.

Re: Gastromyzon ID - mixed bag
I am still not sure. Whatever they are, they are nice looking fish. Did you get them in a store or online?
Also, what country are you in?

Re: Gastromyzon ID - mixed bag
I got them from gunpowder aquatics in Florida (Richard Gelok). I'm in Detroit. I've put Dr. tan's book on my Christmas wish list, fingers crossed! Thanks for your help! Regardless of species, these are some great looking fish.

Re: Gastromyzon ID - mixed bag
Dr. Tan's book is good. Maybe you will be able to ID them after looking through it yourself. Sometimes it helps to look through the different species descriptions and collection notes to see what other type of fish occur in the same streams. Often times you will see that several gastros could be collected together and that might narrow your search.
Since you got them in the US I will keep my eyes open for them. Lately it seems like the only gastros I see are pure shipments of scitulus or ctenocephalus. I used to find them in mixed shipments of two or three species most of the time.

Re: Gastromyzon ID - mixed bag
Richard didn't have a label, we were both trying to figure that out. Right now he has them listed as a "grab bag".

Re: Gastromyzon ID - mixed bag
i saw that, but i just assumed it would be random ones from what he has labled and instock already. i've been doing some intense googling and finding alot of scientific articles on gastromyzon, but its all scanned books (many with black and white photos) so its very hard to see the photos for a good id. (i'm a visual person and just reading a desciption doesn't help me).

Re: Gastromyzon ID - mixed bag
I understand, I'm the same way. I finally caved and bought Dr. tan's book. I think I'm getting closer to an ID.

Re: Gastromyzon ID - mixed bag
I hope you do. I tend to be visual on the ID's myself and Dr. Tan's book helps, but it also helps if you can look at the fish up close and not in just a pic.

Re: Gastromyzon ID - mixed bag

Re: Gastromyzon ID - mixed bag
Actually that's what I meant. I can take the book to the tank and get a better comparison. Dr. Tan's book is helpful in that it has pics of live fish, not just the pickled, colorless specimens that make identification difficult at best.
