Hi Names Mark I have 2 AACF's in a 20g tank Had one for about 6 months and the other about 2 months but I think they are of the same batch since the second got about as big as the first These guys are great I go out in the yard at night and grab them a nightcrawler and in the morning I give them a few Doromin reptile pellets and once in a while a little bit of raw shrimp Well anyways Hey
