my fish are dieing one by one. my 55 gallon tank is nearly empty. my remaining rasboras are in QT along with one of the cory cats and one oto. One of the rasboras is flipping upside down often. I think he is near death. Another one has red dots under its belly and near fins almost looks like broken blood vessels. my oto has big belly, thought he was eating a lot but today he was just sitting at the bottom of the tank all day!! when he finally moved I saw that the whole part under his mouth in between his gills is BRIGHT red. What is going on??? What do I do?Oh and a shrimp died. I just did another partial water change in the big tank, did one yesterday too. And another in the QT. I keep testing the water and the params are fine. no ammo spike, no nitrites nitrates around 20. What do I do??? How can I stop the DEATH???
