I have brown algae growing in my tank and I was wondering if Cory Catfish could clean it. If they could not, what other fish, besides shrimp and plecos, could clean the algae? Just a note, my tank is 29 gallons and the algae seems to be growing on the glass.
Maybe a few herbivore snails? I used to own some and they were pretty good, but they reproduce fast so you might have to take out a few every month, but they scrub away thing rather quickly leaving a clean trail, Cory catfish can do a good job too.
If it’s a big problem, you could shorten the duty cycle of light so that the algae don’t grow as rapidly, I honestly have had that issue before, so if it’s over growing, you could always try that.
Thank you for reading this answer!
Bristle nose placos do a good job cleaning out algae. Make sure to get atleast two to three inches large. Perhaps following link would help not down voting.
