ok if i were to turn my 112 into a hamster tank, what type and what kind and how many could i do? i may do that cause im not able to care for my fish well. and may sell my eheim 2250. so any inputs? any other ideas? ( nothing like a snack or repile but easy to care for animal ) and if i sold my eheim 2250 who would want it and how much? if i sold it, that would help me to get started with my hamster keeping.
