I’ve had to work a lot the last week and didn’t do as large of a water change as a normally do. I just got home and noticed my tank was full of tiny specks and slightly cloudy
What can I do about this? It’s a bare bottom 75g with 2 fluval ac70 filters and 2 sponge filters. 2 young common goldfish.

Got him about a week ago from a meijer grocery store. The employee swapped the label with a cheaper one for me because he said he was relieved to see one get out of the tiny cups. I was wondering if anyone knew what variety he was?

Sorry for bad photos. It’s a 36 gallon bowfront. I’ve had it empty for a few months and thought about putting some guppies in it. It’s always had this on the corner what I believed for a while to be a scratch but now am worried it might be something more. It’s smooth on the inside and can only be felt from the outside. If it were a deep scratch or crack would it be safe to put some kind of silicone sealant on it or should I just throw the whole thing out? It’s maybe an inch and a half long

Someone said my fish might have popeye disease. He’s about 2 years old. Was bought as a feeder fish from petsmart. Has lived in 75 gallon with large water changes twice weekly. Behavior is completely normal and eyes just protrude a little but look fine otherwise. I want to add that his eyes have always bulged like this. Surely if it were a disease it would’ve shown some other signs? I make sure there is zero amonia and nitrite often and keep the nitrates low.

Should I treat for ich?
