20 Gallon Long Stocking Suggestions Needed

I'm looking for suggestions for stocking a 20 gallon long. I'm thinking bare bottom because it will be in an extremely sunny spot. I would love to go planted but I don't have the time right now to tend plants. I know a 20 gallon is small. I would love a larger one but the explanation of why I'm not going bigger is below.

Because of a move & a baby I'm a fish keeper without an aquarium for the first time since I was 7 (with the exception of my 3 Gallon Eclipse Betta Tank, a gift from my fishkeeping husband). I'm dying for a new large tank. We sold our old 55 & 75 gallon hand-me-down tanks in anticipation of getting a new larger tank but before we got one we got the surprise we were pregnant. We tried for a baby for 8 years & had come to the conclusion it just wasn't going to happen, so when we got pregnant we put the new aquarium on hold until the baby was a little older. Now we are trying for baby number 2. I still want to wait on the large tank but I have the perfect spot in my kitchen for a 20 gallon long. If we do it right it will look built in.

Hi MrsJones, Welcome to Tropical Fish Keeping.
There are many different kinds of fish that can go into a 20 long but before we suggest any can you provide your GH and PH? I would also atleast add some sort of substrate. It will make your fish more comfortable in tank. Also watch the temp in the tank a very sunny spot can heat up the tank not always but it could. I would also suggest some kind of decoration in the tank to give the fish some place to hide and help provide some cover/territories.

Plants don't really require much time, no more than a non-planted. I think that plants would also help keep algae down with may arise from having a lot of sunlight on the tank. They'd use up an excess nutrients. If you start right with a 6500k bulb, everything else is cake. Fertilize once a week with Seachem Flourish Comp and you're done. Plants also help keep water chemistry so if for some reason you have to miss a water change, it's not as big of a deal.

That's just my opinion though :) I'm with Boredomb, if you can give us the numbers for your tap water (you can usually find this online) we can help look for suitable fish.

Give the small size of a 20 live plants would really be beneficial in there. Most of the fish that will do well in that tank regardless of water parameters really benefit from a planted tank. And they honestly aren't that hard. Easier than house plants in my opinion. Just food for thought.

Yup, because you don't have to water them ;)

Welcome to Tropical Fish Keeping forum.

I second what has been suggested by others, and will add a couple cautions. Taking the sunlight first: Never allow direct sun to strike an aquarium. First, there is the temperature issue; sun heats up water fast, and this can cause real distress for some fish. Second, the brightness of sunlight is something that is foreign to most of the forest fish we keep, that come from quite dimly-lit waters. Fish are not designed for bright light, and this can cause severe stress. Third, from the aquarist's perspective, a sun-lit aquarium is not really easy to view or see clearly.

A substrate is important for fish, as was mentioned. The darker the substrate, the better. Aquarium glass reflects light internally, and this can be very unsettling. There is also the very important function of a substrate biologically. There is good reason for bare tanks when it comes to certain situations like treating a sick fish, but this should never be the norm.

Stress is the major cause of all fish sickness, and stress will occur from any of the above as well as many other factors. Preventing stress is the only way to have healthy fish.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
