Just 2 rays!!!! More like two awsome rays that you should do everything and anything for and forget all the other fish. You will need to do better water changes on that system evem if you leave them in there for a week. Honestly I would be testing the water allot but more likely doing daily water changes with just those 2 rays. They will foul the water super fast. A little stress is better then horrible water anyday. The rays do not look huge compared to the size of that tank so they will be ok for a week to treat them and get them eating, just as I said before change water and change water daily or whatever it takes to keep it super good, use a test kit. While they are in there I would give them lots of fresh water and dissolve salt in new water and add to tank to help with the tail. If its a fungus find a treatment and do it now. The tail looks more torn up vs fungus to me, but It is hard to tell from the pics but im fairly sure.

They´re just 2 rays and I just fed them and they ate well. Wouldn't it be better to wait until the male gets better and then move them because would´t they possibly stress out and die more easily with 2 aquarium changes in one week??
