Unbeliveable

[rookie]

As soon as I noticed my corys had white spots I quarentined them and I thought I got them in time because about a week has gone by and so sighns of ick on my angel. Now today I drip acclamated 11 danios for 2 hrs and I just came back home after them only being in the new tank for 5hrs and one of them has a white spot and alot of them have white on the tips of there fins. What the heck is going on

ps after that I just immediatly treated the big tank

The ich on the new danios most likely came from the shop where you got them. I think you are right to treat the whole tank. Just follow the directions, remove the carbon from the filter if you have any in there, and it is always a good idea to add an airstone when medicating the tank to ensure there is plenty of O2 for the fish.

Bring a magnifying glass with you when you go back to that store!
Its a great way to see the fish.

Yea I took out the carbon about 20 mins after medicating bc I forgot it was in there that should be ok right? I want to make sure there is enough meds but not too much that will harm the fish. Hopefully I can kill this ick in it's first lifecycle
