Ok fishy people... I ended up with 4 female guppies, 3 with pronounced gravid spots, but not bulging bellies, and 1 pretty little male. They've been in their new home for a couple of hours now and everything seems "ok" but I have some questions!!! (Like you didn't expect that! lol)

1. The current from my filter seems a little too strong, especially in certain areas of the tank, but they seem to manage it ok... should I somehow try to alter it??? I did place screening around the intake so that it wouldn't suck up babies, but should I be worried about the current?

2. There's something growing in my tank... the tank's only been set up since Sunday, filter/heater running since Monday and I have little alfalfa sprout looking things growing from the gravel. New gravel, took it out of the bag and rinsed it. Used aquarium, filter, air stone, castle, new plastic plants. Thoughts? I could take a picture, but they seriously look exactly like an alfalfa sprout.

3. Heat.. have a hang-on heater.. water temp yesterday morning was low 70's when I turned on the aerator... didn't check it after that, but was only high 60's this afternoon. Turned off air pump and temp is *almost* 70. Good enough for guppies? The heater has an adjustment on top and I did turn it up a bit this afternoon, but it was already almost all the way up so not sure it's going to make a huge difference?

Help!!! Thanks!!!
