Hello! I thought I had my stocking for my 5g all planned out but then the guy at the lfs threw a spanner in the works.. (bearing in mind everybody at this lfs are hobbyists or professionals) Can I keep two dwarf puffers in a 5g? I know that at young ages they like to band together for safety and all the ones they are selling are quite young. And they get agressive and territorial as they grow up. If they grew up together, would they still be aggressive? How much plant and rock coverage would I need to ensure they had enough hiding spaces? If one grew up by themselves, would they be lonely? Thanks in advance I really need all the information I can get!
