Hello, I'm looking for more info than I can find with google. I really would like to breed them. Both are suppose to be fully fresh water. Schismatogobius ampluvinculus - I found that they are from cool streams(69F-74F), but how much flow do they like? Currently I have 20 gallon quarantine tank setup for a group 8 juveniles that will be arriving tomorrow. It has a canister filter on it that is rated for 30 gallons. Also threw in a sponge filter to add more aeration and filtration. Also stuck a small wave make to add even more flow but wondering if that is too much. If I have some females in this group I'm going to break them down into small groups and try to figure it out. Temp I'm keeping it at now is 74 with a PH of 8 at the moment. Brachygobius xanthomelas - I have a few articles on these guys but nothing concrete. One person claimed to get some eggs but no fry. They had a low ph of 6.0 water and Seriously Fishy info has them 7.5-8.5. Mine are spread out in couple tanks at the moment. Small group of 6 sitting in my 125 gallon community having a ball exploring in there. It's heavily planted and they seem to congregate in the rocky area away from where there is some flow. The group I stuck in a planted 20 gallon munched on some of my orange shrimp and not the babies either. Brachygobius xanthomelas is tiny, and the biggest one I got is maybe an inch. These things had orange bellies for the first few weeks. I had to net out the remaining shrimp. I didn't realize they have big mouths for such tiny fish. The one's in my community tank with cherry shrimp seem unaffected and never seen them bother any cherry shrimp. Here is some pics of my Brachygobius xanthomelas, picture comparing they look to be right ID. Anyways, not sure if the pic links work or not. Any info on these guys would be greatly appreciated!
