Hi all! So I plan to have a 40 gallon breeder open soon and am looking for something truly unique. Not angelfish or glass cats or cichlids, something really unique like South American puffers, or leopard bush fish. Something that will be really cool. I am completely willing to do any extra care needed for these fish. I have kept a lot of fish in the time I’ve been in the hobby and am looking for something new to try. The only requirement is that it has to be freshwater, and can’t be over 100 dollars
