Close. The silver dollar had died.
Welcome to fishlore! How big is the tank? What is the full stocking? How long have you had them? What is the ammonia, nitrite and nitrate? They are schooling fish so should be kept in groups of 6+, 2 is not enough, if something is wrong this will add to their stress.
Hi thank for the reply, How big is the tank? 50 gal running with Fluval C2 and C3 What is the full stocking? 2x Silver Dollar, 2x Angelfish, 4x Upside down catfish and 4x Kuhli Loach How long have you had them? For about 8mths What is the ammonia, nitrite and nitrate? Ammonia is at 0, PH is at 6.8/7 , nitrite and nitrate I'm unable to test as currently I only have Ammonia and PH test kit.
What is your water change schedule like?
25% once per week
Does he seem to struggle getting to the top of the tank or struggle getting to the top of the tank? Does he seem bloated at all? What foods are you feeding him?
No, he's swimming between mid to bottom of the tank and is able to swim to the top and bottom if there is food. Occasionally he will follow the other silver dollar. No, he doesn't seem to be bloated. Mostly pellets and frozen bloodworms
