20 Gallon Tank Opaline Gourami Tank Issue.

V-Star

Hello everyone, I have an issue with my 20 gallon tank. I wanted to start this tank anew and set it up three weeks ago. I am not a beginner. The first fish that I introduced were four lyretail mollies, 1 female 3 male but all thre males different species. The next I introduced abt 4 days later was a male juvenile opaline Gourami. This is where minor problems seemed to occur. I know Gouramis are territorial so whenever a molly came close, they would be chased away. But he did not go and actively trouble the mollies. 3 days later I add a lyretail swordtail and a female opaline Gourami. Also a juvenile, the male would actively chase her but I thought they just needed to adjust with each other. This morning she was found dead with her fins nipped. I did not want this to happen and so many ppl have said that Gourami get together well. Should I be worried abt this for my other fish or is this Gourami just aggressive? If so, I need to rethink my tank layout.

Hi

First of all, mollies and swordtail cannot be kept at maximum comfort in a 20g, IMO. No either can two gouramis. But that’s just my opinion. The gourami might just be aggressive, but you kind of lack the space. Sorry about the loss, look into the gouramis a bit further and you might find answers.

Thanks I suppose. I feel that maybe the Gourami space is correct. The others although seem to be fine in the twenty. I’ll refrain from adding more gouramis. And posssiby create some hiding spots to keep them from eachothers way.

Good idea. Maybe add some Amano Shrimp or snails to clean up.
