Im kinda new to keeping fish but had 2 bettas before.I let a 30 gallon tank cycle for a month before getting fish. For starters, I got 2 Red Wag Platies. I had them for 4-5 days when one suddenly strated floating at the top with white stringy poo and white spots on him. He later started swimming upside down and died that night.
I did a 50% water change for the remaining Platy
and checked the water levels. Everything was listed as okay for the water. After a week, I got two Dalmation Mollies and a new Red Wag Platy
, which had a mysterious hole in his top fin that later split his top fin into 2.The week after,i got two Skirt Tertras and Two Red Minor Tetras. The problem started when my new Platy
started to sit under some large plants and stay still. The only thing moving was his gills.We put some aquarium salt just to help him if he was sick. Today moring, he was happily moving around with the other fish when i gave them food. But 2 hours after feeding he retreated to his "resting place."I am really worried that he will get sick and die and need some help.Can anyone tell me how my first Platy
died and what is happening to the new one?
Any help would be greatly appreciated.
