I have a 5 month old 70 gallon tank with 9 neons, 5 red eye tetras, 1 pleco, 3 cori cats, two mosquito fish my daughter brought home from school,and three balloon mollys. They had all been in there for several months. I decided to get some plants from the aquarium shop here and got some floating sprite and bought four angels. Within two days two angels died. One had what looked like hemorrhaing under it's skin. Nothing else I could see though. No other symptoms. Now I see one of the mosquito fish and all the mollies are flashing. One of my neons was dead this morning. Nothing on his body I could see either. I had started treating for ick secondary to advice from the aquarium shop owner (40 years experience). I do a 25% water change weekly. In the big wad of floating plants I bought there were some type of fry. The remaining angels won't eat, but are constantly trying to catch the fry. One Molly looks like maybe (hard to tell with his mottled coloring) that there is some fungus at the top fin. But again can't really say 100% because of his mottled coloring. He does however flash the most and is at times almost like standing on his tail for a bit of time. I started Maracyn Two today on the advice of the experience guy, but I'm desperate and don't want to lose the rest of my fish. ANY IDEAS GREATLY appreciated!!! I did not quarantine (won't ever make that mistake again and also did not "salt bath the plants". Being a newbie really stinks sometimes any help is greatly appreciated.
nitrites and ammonia 0
I use API testing kit
forgot to add the mosquito fish which are closely related to guppies keep dilating their eyes until they look like huge black eyes (not bulging though) so I'm assuming this is massive stress????
