Yeah, don't do it. I could be wrong on this but there isn't a species out there that can survive in such a tank. What specific tetras were you looking at putting in there?

Neon tetras, main concern is will the water need changing more just because the tank is smaller.

If you have very very light stocking and test the water regularly then you might be able to get away with slightly less water changes.

The fact the tank is small though will likely mean you will need to change the water possibly once or even twice a week.

10g Fry / Hospital / QT tank (as needed)

75g Saltwater Reef, Ocellaris Clownfish, Lyretail Antias (baby), Lemon damsel, Longtail Fairy Wrasse, purple dottyback, snails, crabs and a few LPS corals.

220g Still sitting empty (come on Lottery I need the numbers to come up!)

Thanks,
Logic was telling me If a 5 gallon was lightly stocked, I should be fine. I'm getting the message though that it will require more changes. I should restart the 10 gallon. liked the 5 gallon though, just don't have alot of room, thanks for the replies.

Basically the smaller the tank the more water changes need to be done as there is less volume of water to dilute pollutants.

A good thing to remember - The solution to Pollution is Dilution meaning more water changes.

10g would be better off if you can fit it in.

I agree. Plus Neon Tetra are a shoaling fish and should not be kept in numbers less than 6. They actually greatly prefer larger shoals as they are a small fish, and they've been geneticaly programed over hundreds of years of evolution that there is safety in numbers.

Almost all small fish are this way, and due to that a 5 gallon isn't suited to much of anything. Personally, I'd only keep a Betta with a couple shrimp or a snail in one that small.

Agree, a 5g is not sufficient size for any of the "normal" tetra or cory because they must each be in a group regardless of their individual size.

We have fish profiles, and most fish are included. Second tab from the left in the blue bar across the top; info on numbers, minimum tank size, and other issues are included for each species. If the name is identical in posts as i the profile, it will shade, example Neon Tetra, and you can click the shaded name for that profile.

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]
