With cubans, once they stop eating they will eventually get the bloated look, right before they die. When I treated these guys, I placed them in a 5 gallon with plenty of oxygen. I raised the temp to 86 and used epsom salt. I did 50 percent water changes daily while adding epsom salt accordingly. I did this for 3-5 days. During this time, do NOT feed the fish. I lost some, but most would start eating again, and were moved (they should be moved to a quarantine take where they can be nourished back which is an even longer process. They can always loose their appetite again, so this stage is critical.)
This is the most succesful way I treated my cubans. With some, you will have to repeat the process. I did this a few times using metro also. I only used metro for the nicer fish over 2" since metro is more expensive than epsom salt.
It looks like you are already doing this with the epsom salt and metro. Just keep up with the water changes and correct dosing. But, more imporatantly, do NOT feed them until they have gone through 3-5 days treatment. 3-5 days depending one how active and stressed they become. Not all fish (cubans) are healthy enough at this size to make 5 days in the epsom salt.
