How to cure a risen bump?

DO YOU THINK I CAN MIX API-FUNGUS CARE AND API LIQUID SUPER ICK CURE OR BETTAFIX TOGETHER.?

• Hello, I bought 5 Betta's from pet land- 3 Male 2 Female, and 3 Pearl scale Goldfish and a Black Telescope and a Gold Mystery Snail. Plus 3 small female Betta's from a local pet shop. First of all, Pet-land employees are so retarded to me. They don't know anything about fish, except from what they learned from their customers. I told the guy who worked there for years and that a goldfish has popeye and he said what is popeye? smh. Also the manager told me Bettafix fixes columnaris, and fish lives without they eyes.Crazy Right. Anyway my fish are going through it 2 Betta's died. 1 Male and 1 Female the female [Kim] was covered with white Cotton like patches which consumed her body the next day and she died due to her not being able to swim to the top for air. The male [Denrek] died by always floating at the top, not eating, turned gray and he had this bump bulging from both sides of him right beneath his dorsal fin. Now my Yellow/black pearl scale [Mc Rob] has red tiny spots on his skin and is not active as much as the other fish, Still swims around and eats. The Other female betta [Chloe] has something that's like white and a little puffy coming from her butt hole area, but its not consuming her. Little less active then before. My other female [Courtney] has a patch next to her dorsal fin and its healing but idk where it came from shes not active as much. Now when i was at pet-land i told the guy my betta died [Denrek] and he felt bad. Better yet he gave me a male betta [Fin] with a case of Fin rot. Last My female [Tamera] has red dots on her swimming fin and has a piece of it missing, and a piece of her back fin came off but it has little white dots on it also she sits in the bottom on the tank squeezed under the the aquarium plant and only comes up for air and since she is kinda see through she has something red inside of her where the tail begins. I bought some aquarium salt, fungus cure, bettafix, liquid super ick cure all from API. I have my 4 goldfish and 3 betta in the tank with some fungus cure and aquarium salt. Can Fungus cure be mix with any of those medications?. My fish chloe,fin,and my other betta Murrick which nothing is wrong with him are in separate hospital bowls being treated. What should i do? I Have a filter i always filter and hour before putting them back in, i condition water, make sure its the right temperature and have a thermometer. Always clean net after each fish transport. i clean plants and let them dry fully. what should i do?

• Answer:

  Just be careful about mixing medications together. Fin rot is a bacterial infection where fungus is a fungal infection, so both have different chemicals in the meds. It is possible to over medicate a fish. I would suggest trying to find a cure that treats everything. I know that Aquisol is really good and the other day I saw another liquid med, but the name escapes me. Also adding aquarium salt to any tank helps promote the fish's natural slime coat that keeps is safer from disease.
