I noticed some grey-green stuff on the suckers of my heater, which I'm guessing was algae, but now it's mostly gone. Could my fish have been nibbling at it?
I have never seen my zebras eat the algae that my tank had when it was still new? I guess it's possible, I mean zebras are very active and different personalites, one of my zebras eat my pleco's food from the bottom, and none of my other zebras do that, do I guess ? LoL
anything's possible, i mean, mine eat everything except for tubifex worms ?? weird i know. but they eat algae discs too, but have never touched actual algae.
