Nope, no soap when I cleaned out the tank.... I used really diluted bleach water and then rinsed it all out good and let it air dry for a few days. I started cycling it and I like the idea of DP's, but I have to check and see what my local pet store has. I am in the dorms, but I have my own room, so live worms in the fridge isn't a problem. If my pet store has DP's, is one or two better for a 5g? I just don't want to overstock and its hard already since its only 5g. If they don't have DP's, how many guppies and snails could I put together? It would have to be one betta because three females in a 5g tank is too much right? Thanks again for all of your help!!
