[Ripley]

Thanks for your help, guys. I hadn't thought of bottom feeders - probably because I tend to not like the ones I've seen. But, definitely something to keep in mind. I kind of thought bettas and guppys wouldn't go well together? Because of the guppy's bright colours and big tails.

Between the platies and swordtails, is one easier than the other to keep? I had two platies before, and they both ended up with terrible fungus (stupid PetsMart) and died. Just want fairly hardy fish.

The betta's not an absolute must, but I'd like to fit him in if it works with the big tank.

Thanks for your suggestions! I'll keep them all in mind when I go shopping (once tank is set up and cycled). Other suggestions are still welcome, if you want.
