While we're waiting for the water parameters of your tap water [GH or general hardness, KH or carbonate hardness or Alkalinity, and pH] which you can get from the municipal water people: do you have a tank light? I saw the other thread but there was no light in the photo. Live plants are very useful in tanks like this, and this is easy with a decent light.

We need to know the water parameters. Some fish must have soft acidic water, some must have hard basic water, and some will manage in the middle. Knowing the water is necessary to narrow down oiptions with fish. It is much easier and wiser to have fish suited to your water, than to decide on fish and then have to somehow adjust the water parameters which can be done but can be very involved and expensive. My article on this will explain the relationship:

Second point, is that filtration depends upon the fish, so it is best to know the intended fish before spending money on filtration. And live plants helps out here too, by filtering the water better. And there are some fish that must have the cover of plants or they will be stressed. So that is why I asked about light for plants.

Most of us learned the hard way--by losing many fish--that all this has to be sorted out before fish are acquired.:)

Your water parameters are important as is mentioned, but I won't harp on about them. The million dollar question is do you have a species of fish that you like, or a specific fish you like. I noticed you keep a few different kinds of tetra. I'm investigating/researching shrimp ATM for my future community tank of tetra. Could I suggest you choose a specific type of tetra and dedicate the 20g to a single school of them. The fish profiles in the top left can really help in narrowing down the best options. My two cents
