These fish are great at keeping algae under control. I’ve had them for six months and they’re active and healthy. I keep them in a 30-gallon tank with a group of five. They don’t bother other fish and stay calm most of the time.

They arrived quickly and look healthy. I noticed a reduction in green algae on the glass after a week. The dark stripe is very noticeable and they swim gracefully. I recommend keeping them in groups.

I added two Siamese Algae Eaters to my tank and they immediately started eating algae. They seem to get along with my other fish. The tank looks cleaner now, and they’re active without being aggressive.
