As a general rule, rummy nose tetras should be kept in a 20 gallon tank in schools of They would not do well in a 5 gallon tank because they can get up to 2. I would recommend choosing to have a school of 6 neon OR cardinal tetras. And then you can add a snail Nerite snails are pretty and good for a 5 gallon. Newbie fish owner here, hello. I just bought myself a 5 gallon tank. Is it better to keep the same type of tetra or is 2 types alright? Also, would adding ghost shrimp or red cherry shrimp be okay if so how many for this size tank?

Any help is much appreciated! Thank you! I have a 29 gallon tank with 3 harlequin rasboras, 3 von rio tetras, a dwarf Gourami, a rubber lip pleco, 2 Amano shrimp, and 2 Nerite Snails. How many cardinal tetras could I get?

Hey there, if you are going to get tetras neon tetras are small and you should get a minimum of 5, which you could possibly get away with. I would get a half dozen shrimp and see what happens, then maybe try tetras.

I have a 5 gallon tank and my fish are overpopulating it, but I am not aloud to get a 20 gallon tank. What do I do? Recently bought 1 Male beta and is on a 3.

And how many. I would say no. They say 1 gallon for every inch of fish and with a betta its probably only big enough for it. You can though get an African Dwarf Frog.

They are an amazing option. They are docile and will leave your betta alone. And they only need 1 gallon per frog. Do your research on them, and you can probably have 2 in there. I was wondering if this amount would be alright for a tank of my size? Or should I rethink my plans? What you are planning sounds good to me!

I think that all those fish would be happy with that size:. You could add shrimps. I am thinking of getting a 23 litre tank 5 gallons and would love to get neon tetras. If I got 6 would this be ok then? And are they ok on their own or should I get companions aswell or is tank size too small for that?

Or do you have any better recommendations for this size tank for neon tetras? Hey Rebecca, Fluval edge tanks, even 5 gallon ones, would be great since neons are schooling fish and you would also get an extraordinary visual experience. As a companion, I think one Nerite Snail would be perfect! Nertile snails are great tank cleaners, one of the best algae eating snails around.

Looking to put them into a 29 gal, not sure about how many neons? Only other fish will be one pleco that stays small and one adf. That is the reason why they usually tend to get along together. Since you are planning on a gallon tank, I think a school of Neons and Betta will work great for you. Tetras are schooling fish so have a minimum of six. With your tank size, I think you should go with twelve of them.

Plecos tend to stay at the bottom of the tank so it will be great tank mates with betta and neons, as long as it stays small. Adf, on the other hand, may not be a good addition, especially with bettas. The main problem that could arise is betta eating all the food before Adf can get to it. You should go with a couple of snails instead!

I recently bought a 6. Hi, I have a betta in a 15L tank and two days ago I added 4 cardinal tetras and 3 snails. The betta has been moping about since they were put in. Have I done the wrong thing? Looking forward to hearing what you think. I suggest keeping the betta in a different tank because betta fish need their space.

One Betta needs at least about 2. If the tank was a lot bigger, you maybe could put other species with a betta. Hi, I want to stock my l tank with low bioload and docile species. In order for me to maintain good water conditions with weekly water changes, what is my best stocking options? You can always add more fish! Hi, I have a 10 gallon tank with 2 guppies, 2 glofish tetras, and 2 African dwarf frogs.
