How many 2" clown loaches can I quarantine in a 29g? Filtration is Penguin 200 and Penguin 350 and 2x Koralia 1. They will be going into my 280g w/ 15 established loaches from 3.5-5".
Do make sure you quarantine them for 3-4 weeks. The longer, the better. Patience will pay off as you will not have to deal with future issues frequently in your larger tank.
FSM is right. Overcrowding has long been the perennial problem for most health issues that it is harder to treat your fish in overcrowded conditions as they are stressed constantly by the poor conditions.
