I have 3 BPs 2 female and one male, all three are living together in the same 75 gallon tank. They are all heathy and happy they eat regularly they shed perfectly ( all in one piece including eyes ). when i take them out to clean the tank (twice a month) they all explore the house together, almost like a pack . But i have had people telling me lately that housing them together is a bad idea. Obviously when they feed i seperate them but other than that they seem to be good. Any advice?
