thanks for the offer on the guppys but i have a tank full already. Actually a friend of mine got some green spotted puffers the other day and she found out they're just like little kids, they don't want ot eat there veggies. So, what she wanted to do was feed the ghost shrimp algae and then feed the puffers the ghost shrimp so that way the puffer gets veggies and meat all in one bite.
