Think I'll be keeping my 200w heater on one of my 55s just so I have 2 in case one fails.
After Angelicus Loaches, I'd also like to move back to another set of clown loaches, but I think a discus tank plus being a 120 is probably too small?
A proper shoal of clowns with the rest of the stock will be too much for that tank for life in my opinion. I have 6 clowns that are 5"-9"+ in a 120 right now, with a new tank on order to upgrade...
