For me, it’s natural-looking rocks, roots, and aquarium-safe wood, but if you want to have a ceramic castle or a SpongeBob Pineapple House, you go for it. Decorations in a Neon Tetra tankĪs with substrate, I don’t think Neon Tetras really have a preference for what decorations they have in their tanks. The bright colors of the Neon Tetras really do pop against the light, sandy background. Personally, I use a lot of sand in my display tanks at the moment. I have kept them in tanks with gravel and tanks with sand, and they thrived in both setups. I don’t think Neon Tetras really care what substrate they have in their aquariums. In fact, in my experience, the more Neon Tetras you keep in a tank, the better they look. Neon Tetras place a fairly low burden on an aquarium, so you can keep a lot of them in one tank. If you had a larger tank, maybe a 55-gallon (200 liters) you could easily keep 70 or 80 Neon Tetras. For a 20-gallon (76 liters) tank, I would probably look to keep 20 or 30 Neon Tetras. As a schooling fish, 6 is really the minimum number that should be kept together. You simply adjust the number of Neons to match the size of the tank.įor a 10-gallon (38 liters) tank, I would keep 6 Neon Tetras.

Neon Tetras can work in just about any tank size you have. Both tanks are essentially set up the same way. I currently have a small group of them in a 10-gallon (38 liters) tank on my desk as well as a large school in a 155-gallon (600 liters) tank in my fish room.
