Pet store/farm bred guppy, I've had her for maybe six months or so, not sure. She hasn't been the healthiest fish, her first batch of fry only two survived, and she had some swim bladder problems just before dropping that first batch, seemed like the fry were pressing on her swim bladder a bit, but it was only minor and she was back to normal after dropping the fry.
Then there was a battle with worms in July/August and she was very sickly, came close to losing her then, but she bounced back after medicating the tanks.
She dropped her second batch of fry on Friday, 38 fry counted, maybe a few more, and she has seemed okay since then. Other fish and shrimp seem fine too. I've been doing large daily water changes on this tank for the last two weeks and counting though, since it seems the ferts I added have pushed the nitrite levels high every day. Removed a bunch of those ferts a couple of days ago, still getting nitrite readings and doing daily changes, but nitrite levels are dropping, not getting as high between daily water changes, and fish and shrimp are still behaving normally - no gasping, fin clamping or staying near the top or the bottom.
Found her dead when I turned the lights on today. Have tested the water and zero ammonia, nitrites 0.25ppm. Not what I want, but lower than they have been at times recently. Could this be a result of the nitrites accumulating inside her, even if she didn't show symptoms of nitrite poisoning? She seems to have bled internally.
