Hello all , Im new to the forum . Ive returned to the hobby after a 25 year absence. I have been battling blackbeard algae in a 20 gall tall. Ive read many comments on Siamese Algae Eaters as a commonly known fact that they are one of the few that will dine on it. After shutting down a airstone , I patiently watched my Chinese Algae Eater polish off one side and then the other of the air stone of all the Black Beard Algae. Probably just as well as a slime coat ! haha Just thought the CAE deserved at least one good attribute among all the bad press.
