Hatzie update, one eye looks normal! The other is still puffy but I think it looks darker/ less hazy. Just did a water change for him and one for Stormy. Hatzie's Nitrates were at 50! That is the highest I have seen in my tanks. But his ammonia was 0. With no filter? But he does have happy live plants that grow fast. I thought Nitrates were a by-product of an actual filter loaded with beneficial bacteria. ? And since he didn't have a filter I only checked ph and ammonia for him. I have a lot to learn. I try to take care of these precious little lives! I read often about bettas but so much info is confusing or advice is contradictory.
