Hi I am new to this site and have a question. I have a apple snail who ignors my live plants and I was wondering since I have a 20 gallon tank, could I get a algae eater also or should I get another snail? thanks!
You can get several ottos in that tank. They are comfortable in groups of 5 or more but three would be OK. They have great personalities and are constantly working.
The rubber-lipped or bulldog pleco (aka Chaetostoma milesi) would be another option for this size tank. I've had it and three or four otos in a 20 gallon long (not at the same time) to keep algae under control in the past.
