So I breed rainbow fish and gudgeons and have had a lot of fish but never gourami. I also never buy fish from pet stores. Well my ma and pa lfs where I go for frozen food had these guys. Appears to be male and female but they said they got them on accident. They have had them in tap water for a purple weeks they said but they appear fine. Couldn't pass them up. I know that some smaller gouramis require some special attention. I can't nail them down. Can someone help me out with a positive id? They are beautiful fish one with much more pronounced fins that are quite red. I have them floating in a 20 long planted with amano shrimp and 5 small thread fin rainbows as that's the only tank that isn't super busy with larger fish. Thx!
