I was real patient on getting my Nano started up- 14 gallons- waited 3.5 weeks with good healthy lve rock w/ lots of growth- actually never got ammonia or nitrite readings > 0, and went to my LFS last week- thats where I made my BIG mistake- I bought two clowns, a banded coral shrimp, and a BTA- I know, I know- shouldnt have done it, the LFS said it would be fine, didnt do enough reseach- now Im stuck with this BTA I am afraid is going to crash any day and the shrimp is terrorizing my clowns- they dont look so happy sitting in a corner- the only thing I am happy with is my two arrow crabs I caught diving yeaterday and 2 little hermits. I called the LFS, they said the would take it back and give me 1/2 price back AS IN STORE credit! What should I do , take the hit? or try to keep the BTA alive- he looks great right now but everything I have read on this site says its only a matter of time before it dies and kills off everything.
