So I just bought a couple of Clown Pleco (L168) for my four foot tank to help with the algae growing in the tank. I find it funny that I can actually order fish online and have them sent to me by courier. I have the tank setup with 3 pieces of wood for them to rasp on once and they are a number of good hiding spaces, I have a couple of breeding caves for them to hide in though I don’t know if I will get a male and female. I have good water current but I am thinking of getting a second filter to augment the canister filter I have now. Currently I have 4 corydoras and 3 clown loaches in the tank. I plan to get sinking algae food and some sliced cucumber to supplement their diet, but I wonder whether there is anything else I can do for them?
