Filtration For A New 20h

[elliott78]

Hello, I'm going to start up a new 20H gallon tank. I would like to eventually throw a few dime size angels in it after cycling is complete, along with one amazon sword, some gravel and a small piece of bog wood. My question is this... what filtration would be appropriate. I would like to stay away from a hanging filter and was just thinking of perhaps having a couple of small sponge filters and a heater. Any suggestions?

Either a couple of air driven sponges or an internal would be fine.

Angels aren't realy suited to a newly cycled tank, they prefur it a little more mature

I'm shure you know the angels home will need "upgrading" as they grow, as 20g for a group isn't enough. A mated pair would be ok in it, but not a group

All the best
