your algae questions are not really relevant as you have to feed all your fish, including plecs and corys with a suitable diet. So more to the point, what size is your tank, what type of plec and cory do you like and what temperature do you keep your water at?
I plan on a bristlenose and possibly
a golden nugget still not sure of that, my tank is 200L so has plenty of space for these two plecs, the corys I like are panda, peppered and three line corys, I know they are schooling fish but I was wondering anyway if I could have for example
3 panda and 3 peppered and they would school together? I know I would still have to feed them but it was the man at the fish shop that told me that I would need to wait 3 months for algae?
My tank is kept at 26 degrees. My main worry is PH it seems to be around 6.5 and I would rather it was 7 but I don't want to faff around too much with it?
