Hello! I signed up here a while ago so I could look at the pictures and do research before getting a tank but I still haven't introduced myself. I have a 20 gallon tank that has been set up and going well for quite a while. Just a few days ago I got sick at just the same time my tank started getting cloudy (as in when the fish went to the back of the tank it disappeared). Once I got well enough I checked the tank to see what was wrong and I found my black mollie wedged between a rock and the side of the tank. My guess is it got stuck and couldn't get out. I removed it and changed the filter since it was pretty gross but didn't do much more since I still felt rather ill. Today I am setting up my small 6.6 gallon tank I was previously using. It has nothing more than a light and a heater (no filter). I'm guessing the only thing I can do is move the fish to that tank and clean the 20g out real good and change all the water. The fish are probably already very stressed and there is no way to cycle the 6.6g tank first since It has no filter anymore. I'm guessing its the only thing I can do though. I'm sort of new to fish keeping but I read up on it before I got the 20g tank. My 1 question is...is there any easier or less stressful way? If you can please answer within 12 hours I don't want to wait any longer because by then my fish could be dead, and sorry if anything doesn't make sense I'm kind of loopy from being sick.
