Hey everyone i am recently new to owning a tank! i am very excited about it. I acquired a 30 gallon freshwater tropical tank for free, it was fully functioning when i went and picked it up 2 days ago. the tank belonged to a gentlemen who did all the upkeep and maintained it. when he passed his wife gave it to me. now she had mentioned that she cleaned the filter but that was about it. I am concerned that because she wasn't sure what she was doing, she probably washed out all the good bacteria. My question is. i have the tank setback up at my house now all the fish are in it and its functioning, although i think it needs to be recycled. how do i recycle my tank if the fish are currently in there? the water seems to have quite a bit of debris in it from the fish. Do i just do frequent partial water changes until the filter can catchup? also i am having a hard time finding out exactly what kind of fish they are, from what i've gathered online there are 6 neons a couple molly's and a bottom feeder. if these are the fish i have what is the recommended water temperature?
