My system is now completely cycled through the fishless cycling but the place I am going to buy my tilapia from will not have any available for another month. I want to get some fish from the local pet store to put in the system for the time being so I can stop dosing ammonia so frequently and be able to watch some fish!

Not being very knowledgeable in the fish world I wanted to see if any of you had some ideas of what I might try. I put in a plecostomus and a goldfish to start. I would like to have fish that I can keep with the tilapia when they arrive but that wont hurt them or be hurt by them. Thanks for the suggestions.
