My sunburst Mickey mouse Platy that was hiding and liked to bottom sit died overnight. I found her in her corner of the tank. I thought something was a little off when she would not come up with the others to eat last night. The other fish were not harassing her or nipping at her as far as I could see.
I have only had the Platys since Thursday...
The other fish are all seemingly fine. I tested This AM. Parameters were ok. Nitrites were detected (just barely registered), Nitrates about 20 and Ammonia was about .5. Not great, but not enough at this point to be terribly dangerous. I thought the cycle was done! Could it be that the guppies may have dropped some fry?
I did a 25% water change on Thursday. I will do a water change tomorrow. Should I do a bigger change? I don't want to stress the others out with a huge change.
In my 10 gallon: 3 little neon tetras, 3 guppies (1 male/2 female) and (now) 2 Mickey Mouse Platys.
My question: Are the Platys ok with just2 of them? I think one is male and one is female. I do not want to replace the female sunburst to have her die again. Any help would be greatly appreciated.
