Hi guys, Long story short my 30gal is a fun planted community tank. I got some cardinal tetras, leopard danios, bunch of guppies (most of them not adult yet). I had to rehome 5 of the pregnant female guppies because I don't want my tank to be overcrowded with guppies. I'm allowing the small guppies to grow up in there for now and will rehome more in the future. Now my mom is sad because she really liked the pregnant guppies because they were chubby and super personable. The remaining fish are hooligans who eat their food and go back to goofing off with their buddies. Would you be able to recommend any cute medium sized centerpiece fish and how many? They must be personable and can live in peace with the rest of the community. Thanks!
