I came home from school 10 minutes ago, and my fish is not well. He isn't really responsive and is just lying at the bottom of the tank. It isn't a 'rest' kind of thing, he looks quite unwell.

Do a small change and be sure to add your conditioner to your water. Sometimes it can be forgotten and the fish will be fine, but other times it can cause drastic issues.

If his eyes are clouding, inspect everything in the tank for any chemicals or colors that could be leaching. Check his heater for any leaks or cracks.

If you find anything suspicious, remove either him or the item from the tank and do an immediate 100% change.

Cloudy eye is usually due to a water quality issue, so just be sure to do extra water changes to help him out. If it gets really bad, then you could start with an aquarium salt treatment and 100% daily changes. If his eyes start swelling, use epsom salt instead. 1 tsp/gal is the dosage.
