Well, judging by the brochis "tummies" & color I'm going to guess female behind a "possible" also female or male...hedging my bets, lol.
Your pandas are hard to say. The longer bodied 1 (both on the right) look male to me. The "other 1" doesn't really look female, maybe the last "left" fish. Feed them up & post new pics in a month or so, I may change my mind.
I am going to say you need more of both species
Enabling you!
