Hello I am new to aquariums. I recieved a 55g freshwater tank with 15 or so fish, chiclids I think. I wanted a tank for so long but wanted to research it first. Well a coworker just showed up with it. The tank is set up with old gravel dirty and 1/4 of the old water in it. The however are still in a 5g bucket with an airator in it. I know this is not what should happen but it is what it is. What do I do for these poor kids (fish)? I want to make this work.
