I wouldnt really call this a emergeny because i dont thinkits deadly but i was just wondering why my oscar spazzed out today he just did like twitched and started breathing heavy for a lil bit now i know everyones gona ask my water conditions and im on vacation and i can telll you everything is okay but my nitrates there a lil big above what id like i also put a seven day feeeder in idk it thats why

I would say check for ammonia ASAP. maybe the feeder over done it and over fed them, this could lead to ammonia/nitrite spikes, this is the reason we ask for water test so often. it could just be a little to much food and your filter not coping with the extra load. but then again without a proper test its a guess.
