Damn bro, I know that feeling!! I have a 40gallon reef tank.. I threw a party one time at my house and the next morning my water was all F*cked up!! Some idiot probably thought it would be funny to pour a lil beer in my aquarium to get the fish drunk

.. Long story short, I spent all day setting up a dozen quarantine's but ended up loosing about $300 worth of shit (fish included)!!
Next time instead of spending $600 worth of fish all at once u should make sure ur water is good and maybe one fish at a time.. softens the blow bro..
