hey guys i have been doing reading on pygmy chams and i wanna get some i just don't know what species of pygmy to get...do you have to have 2 or more living together? would all females be ok because im not trying to breed.
No that would be okay for just 2. Rule of thumb is 10 gallons per cham in there.
From the people I have talked to, they recommend 10 gallons for the first pair plus one for every 10 additional gallon. so a 20 gallon long is big enough for 3 as long as there is only 1 male.
