I am about to start stocking my discus tank and can not find any logical reason why people say to get an odd number of fish. I am planning 7-9 fish. would like 8 since I can get 2 varieties with 4 of each. but to go odd would mean 4 and 5 of each. Is there anyone who can explain why the odd number.
Oh, they will be in a 110 gal tank
