Hey guys, the person I bought my recent pygo which made my shoal to 11 nats has some caribas around 2-3" and asking if I want some.... Should I buy another 60G tank and add like four in it or should I try adding one with my nats? I know the 80g is too small, but I wanted to try it. he is selling one for $30. Should I try it just to gamble? I awaiting on a good deal on a 160-200g tank..
