Hey guys, I will be aquiring a new 29 g tank in the next few days. This is a used tank that is already set up for freshwater and has a few occupants. I think she said it had a couple mollies, fancy gups and a couple plecos. Oh and I am pretty sure she said it had a beta. My question is, how should I handle things when I get it home. I am assuming we will be taking some of the water out for the trip, I doubt I could carry one full. SO how much is safe? When can I put my danios in? Currently I have 2, 2.5 g tanks with 3 danios a piece and one has a small pleco. Or should I get the tank without the fish? I am really excited, and I wanna make sure I do this right, so lay it on me!
