Any ideas on how to best add a filter to a small existing tank? I can't get another tank to cycle it, etc. There is no equipment in the tank; so far it's done okay on plants and frequent water changes (I've had shrimp in it for about four months now).

The only animals in the 5 gallon tank are three Amano shrimp (who are very special ). I'd like to make their habitat as nice as possible (hence the addition of a filter).

I'm thinking the best kind would be an adjustable exterior power filter with some foam stuffed in the intake and output areas, since it would provide mechanical filtration in addition to biological. I know a lot of people on this site use sponge filters. Any suggestions?

Thanks!

No special needs in adding a filter to an aquarium, unless you are replacing an existing one. With your tank just add one on and continue your regular routine for a few weeks to give the media in the filter time to establish. If all you have in a five gallon is a trio of Amanos there isn't much bioload being given off by them so it won't take long for the filter to catch up. That and along with the fact of having plants that are also helping reduce waste. Filters are really a personal choice and they all have their pros and cons. Sponges are simple and baby shrimp safe, but take up room in the tank and aren't that attractive to look at. If you do go with a power filter you only need to cover the intake if you are trying to prevent baby shrimp from being sucked in, adults don't have that problem.

Thanks so much for the advice!
