So I got my rams two days ago and have them in a 10 gal QT tank w/ heater and filter and doing WC daily, just checked levels and all are fine 0 ammonia. Neither are acting particularly weird but one of them is breathing with his mouth opening and closing and when you look at it on the side you can see a little transparent something coming in and out of his mouth? Any ideas if this is ok or is this a problem?
