I've had my RTGG in her new tank for a few weeks now, all's fine except for slight algae build up on my bogwood and rocks. It's not unsightly or bothering me but if left unchecked it eventually will need sorting. She's in there on her own so obviously i'm the only clean up crew and vacuuming the tank doesn't do much to stop algae. I know that SAE's will sort it in a heartbeat, i have them in my other tank with no algae at all. But SAE's are a shoal fish and i only want one small fish with a low bio footprint. So i've decided to go with just one small catfish that's happy on its own, will happily go about its business, is quite longlived and remains small throughout its life. You guys any suggestions before i start trawling through masses of catfish info on the web.
