I have just acquired 2 colomesus puffers. I have them in a 60l orb and although they require more space they are only 1inch and it is a very heavily planted tank with only 3 other otos as companions, so they seem very happy for the moment.
I am aware that I will need to upgrade the tank at some point and was thinking that if I was going to do that, that I would maybe get some more. My question is what would be the best size tank for 3 and/or 5 adult colomesus?
Thankyou in advance for your help.
