I have a hippotang and clownfish in my tank and just added a small watchman goby, I fed my fish (no spots) today and topped off the water then left until very late tonight. The water had evaporated almost a gallon in my 20.5g tank and now my fish have these white spots that I’m assuming is ich?
I adjusted the return pump to agitate the surface more and cleaned the filter sock in hopes to clean out the film at the top of the tank. There’s white spots in the film and bubbles that aren’t normally there. I already readded the water before I noticed the spots on my fish. The clownfish has maybe 4 spots on the top of a fin - I couldn’t get any pictures of the clownfish.
The goby I haven’t seen since I added him.
Do you have any tips to help me keep my fish alive?
I can’t quarantine the fish unfortunately.
Should I go and get an ich medicine?
Thanks for any tips
