I like 95% sure that they don't sell them where I am. Looks like an interesting fish but they don't have them where I live.
Sorry, I sort of got my facts mixed up about the CAE and the SAE, my problem with the SAE is the tank with the green algae problem is a 20 gallon and I don't think that he will be well suited for that tank since I heard that they get to be about 6 inches.
I wish my green algae problem was a brown algae problem (which I have never gotten since I had fish, even when I try to have it, lol) then my otos will be able to eat it.
I'll probaly add a bunch of ghost shrimp to help the problem.
