In nearly 20 years I have kept several 'Chinese' algae eaters (Gyrinocheilus
aymonieri) and I must say that they don't deserve the bad reputation they got.
I had one for about 12-15 years and it was about 6 inches, ate algae upto the
last minute and lived in perfect harmony with a range of different fish. Some
individuals will indeed turn aggressive and attack other fish, mostly slow
and/or big timid ('expensive') fish, like discus, angels, elephant fish, and
so on. In such a case the solution is to keep them in a school, introduce more
CAE's into the tank (at least 4) and they will leave the other fish alone.
Small schooling fish (like tetra's, etc..) are never victims of lonely
aggressive CAE's. They are good algae eaters, active all day and fun to watch.
They don't eat the long hair/beard/stringy algae because they can't, it sticks
out under their mouth preventing them to get a good grip at the surface by
sucking. But I read they eat those algae at a microscopic level, before they
develop into the 'hair'. They love to eat the green and brown algae, and it's
a hard to compare different algae eating fish with each other, but I read they
have the best developed suckermouth of all algae eating fishes.
