I have a 29gal that was a well-established SE Asia tank for a few years until a tuberculosis/septicemia outbreak wiped out everything. Kept a few cherry barbs in the tank for the last year just to make sure the tank was fully deconned. Now I'm ready to turn it Amazon. Will GBRs leave Otos alone, or should I get a more robust algae cleaning crew, like a bristlenose pleco? Thanks.
