Excess mucous appears as cream, white or grey patches or a film over the fish's body and fins. It can be caused by poor water quality or an external protozoan infeciton like Costia, Chilodonella or Trichodina. In this case there is a small amount of white on the edge of the tail and that is most likely from water quality and not parasites.

Some brands of frozen bloodworms are ok but some aren't. Try to get a brand that has been irradiated. It should say it on the packet. The irradiated bloodworms are less likely to carry bacteria that can make fish sick.
Bloodworms have a very hard head that can't be digested by fish and if the fish get too many, sometimes (it's rare) the fish can get a blockage in their intestine and then they die. You can cut the head off the bloodworms with a pr of scissors if you are obsessive enough but most people don't bother.
Just feed bloodworms once or twice a week and feed other types of food the rest of the time. I used to feed dry food first and then marine mix, followed by bloodworms, brineshrimp, daphnia, mysis shrimp or live food.
If you are going to buy frozen foods, take an esky with you to put the frozen food in and keep it cold on the way home. Most frozen food defrosts pretty quickly even when wrapped in paper at the shop. An esky will keep it frozen longer and there will be less chance of it defrosting on the way home.
If you don't have an esky, take a towel or blanket and wrap the frozen food in that to help insulate it from the warm air.
