Tetras are very delicate fish compared to many other species. They're highly sensative to sudden changes in ph. They will also not do as well if there are only a couple of them. They do well in minimum school sizes of 6 fish. If they don't have buddies, they will be nervous & stressed all the time.Avoid common plecos sold as algae eaters. They get way too big for 10 gallon tanks. Ideal algae cleaner fish for your size tank are rubber lip pleco, and ottocinclus (aka midget suckermouth catfish). You don't really need anything that eats algae unless your lights are bright / left on too long, and especially if your tank is brand new.Be sure you have a heater. 76-78 is ideal for tetras.Expect most plants to die. There are only a few species good for small tanks without a million watts of light on them. Java fern, java moss, and wisteria are the best plants for lower light. You will be best off with plastic plants since there will be no decaying plant matter to foul the tank..Snails are great cleaners. They will suck up a ton of garbage from the tank. Just try to find a variety of snails that will not breed like crazy. To help biological stability in small tanks like a 10g, I often add a sponge filter to the air pump or as a pre-filter to the main filter. They're like $6 and can help bacteria colonize / stabalize tank conditions.
