2 Glowlight tetras and one pristilla tetra. What else should I add?

For tetras to "really" be happy the need to be kept in groups of at least six of their own type, they are schooling fish after all. That said there are tons of tetras, and I mean tons! I will list some cool ones

Von rios

lemon

blue kerri

neons

cardinals

blue

ember

emperor

peppermint

green fire

black phantom

red serpae

Those are the ones that come to my mind right away

not greater fish!! Your tank is already overstocked and the fish you do have in there are not like minded. you will desire to in no way shop a male betta with the different betta (male or lady). lady bettas can effectively be stored mutually yet with the intention to realize this, you will desire to have a minimum of 5 of them and a 20 gallon tank. Glowlight Tetras are training fish and can be stored in communities of 6 or greater and that they could additionally choose their own 20 gallon tank. My advice to you is to maintain the male betta and the snail interior the 5 gallon....this is totally stocked, eliminate the girls and the two get each and every of them their own 5 gallon tank or return them to the save if this is obtainable. If this is not then you definitely would desire to re-domicile them with somebody else. I additionally advise which you the two return or re-domicile the glowlights additionally. i'm sorry if this is no longer what you had to hearken to yet i had to be undemanding with you so which you will grant the final obtainable domicile on your fishies. good success!

For good maintenance, get a small plecostomus and a small albino catfish. The pleco will eat a lot of junk and help keep your tank clean, as will the cat. However, if you pay attention to the catfish, you'll know about feeding. When the catfish comes to the top to eat, you're not feeding enough.

3-4 Corydoras. very peaceful, fun to watch.
