So I bought a MB today (not the one I posted earlier, this one is very healthy and absolutely gorgeous). The owner of the LFS quarintines all his fish so I just drop acclimated the little guy and matched temp then let him roam free. Now, he is doing simething rather odd. The second he entered the DT, he swam right over to the overflow, and started poking his head out the water! My salinity matched his, temp as well. Ammonia and Nitrite 0. Nitrate is 10. Should I be worried?
