Hey guys so I bought a 3-4" hippo tang Monday and have it my QT which is a 10 gallon but I just went to Petco and picked up a 20L to give her more room. For the most part she looks okay, when I put some flake food in there she goes after it. Couple of things: 1. When she is not eating she is lays on her side a lot, is this normal for tangs? 2. I had the 10 gallon running for a couple of weeks with water from my DT with a few pieces of live rock and a AquaClear 20. Before I put the tang in AM NI NA were all 0, today AM is between .25 and .5, am I going through a cyle? I just took out the bio media from the AC 20 and put it in my sump to see if I can get some bacteria and also took an extra piece of live rock from my fuge and put it in the 10 any other ideas? Will putting the 10 gallons and 10 new gallons of water in the 20 help?
