Frozen foods tend to be meat based and have a high protein level. This leaches into the water more readily than dry foods and creates a higher ammonia level. It isn't a real big problem because most filters have enough beneficial bacteria to break it down pretty quickly.
Quite often when a fish (or any animal for that matter) is treated with worms, they will suddenly become really skinny after the treatment. This is due to the worms being expelled from the body. Sometimes the fish or animal is so full of worms that they appear to have a normal shaped abdomen, yet it is shaped by lots of parasites. When the animal is treated the worms die and are expelled, and this can make it look really skinny because there is nothing inside it to make it look nice and fat. Over the next few weeks the animal or fish will gradually fill out and start to look normal again, but this time it is because the fish is digesting its food properly and is not full of worms.
I saw an extreme case of this when I treated a tank of fish I had. There were a few large female mollies in the tank that had never bred in the year or so I had them. The fish looked normal and were always fat but never produced young. I didn't see any worms hanging out of them and didn't think they had any problems. Anyway I treated the tank as a precaution because I had been feeding a lot of live daphnia and the pond they were collected from had water birds and snails in it. (These are often part of many worm's life cycle).
About an hour after I treated the tank for worms I noticed one of the mollies doing long red poos. Upon closer inspection I could see these 1inch long red worms being expelled. 24 hours later and all the fish in the tank looked skinny, especially the female mollies. I treated the tank again a week later and within a few weeks of that all the fish looked nice and fat, and within a couple of months there were baby fish everywhere. Even tho the fish looked healthy, they were artificially fattened by the worms living in their digestive tract. Once the worms were expelled the fish lost all their shape and looked really skinny.

I've read they like their rest and someone had actually written they thought theirs was dead because it was so still on its side and inactive! Maybe it's something to do with sleep interruption from tankmates so they make up for it in the day?!?! When he's out and about he looks absolutely fine now. Fins fully out and he's very friendly. What tanks do you have snowflake? Maybe they're more stressed being in the hospital tank. As for the black blotches, mine develops these if he's ripped a fin. Seems like part of the healing process, then they fade.
