If you can skip a day without water change, and ammonia/nitrites don't rise, then this is good sign assuming fishes are present ,and not too numerous for particular volume of water. Is also a sign that biological filter is working as it should. IMHO
interesting. my tank is 20g and 4 weeks old, with 4 platys. in wanting to keep the water good ive been doing 25-50% changes daily. i had 3 platys for 3 weeks and added 1 who turned out to be aggressive. i returned her and traded for a calm one. but now two of them are staying at the top with mouths open.not gasping really but open. i assume the waters good or all 4 would be at top. is that correct? any idea whats wrong or what my next move is? feeding limited 2x a day,half of that is fresh vegs
