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.

If you have any driftwood in your tank a bristlenosed cat would be a good addition. They won't bother your plants and stay fairly small.

Also take a look at Amano Shrimp. In my tank they have been the most effective algae eater of all, including a bristlenose pleco and several otos.

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.
