I am taking the plunge in a small way, in the shape of a 22L tank. I will set it up in the garage so there won't be extremes in temperature and it will get a short time of a sliver of sunlight when the sun goes past that part of the room. In there I will put my bugs caught in the sheep trough (and more when I go hunting again) and I will be going hunting some shrimps and the like later.
Questions:
Who: If I am lucky enough to catch a bullie or 2, will that tank big enough, or should I let them go and stick with shrimps and trough bugs? My original idea was to grow bugs for feeding to the fish only but my fish-greed has returned and I wonder what else could be kept. Is there a limit on the amount of shrimps that should be kept?
Filter: Presuming I need a filter, is one better than another? I don't want much current in a little tank, so I was thinking of a hang on back filter, or a little corner sponge jobbie.
Light: I think filtered daylight from the other side of the room is enough light, please correct me if I'm wrong. There are no curtains on the room so they will get all naturally occurring daylight.
