Hey guys. I picked up a 2"+ peacock Mantis a few days ago, with the plan to keep her in my sump. That worked for about 3 hours until she got out into the sump. Anyway, I got her out and put her in my 15 gallon with sand, rock and PVC. My question is, she eats mysis like a champ, and I only have a small Tetra HOB filter and a powerhead. What size filter should I get?
