Neon Tetras in a planted tank

New Neon Tetras

I have to admit, these amazing little fish were an impulse buy, neon tetras.

Neon Tetras are one of the most popular fish in the aquarium hobby. However I have never really kept them properly. They’re small, cheap and very colourful.

I bought 6 of them, to go in my little 30 litre, Dennerle Shrimp cube. They will be moved to a larger tank in the future. But for now they’ll do great in this little tank.

So my Dennerle 30 Litre Shrimp Tank, is my shrimp tank. Shrimp only. However it’s been looking a bit sorry for itself recently. Plants are doing amazing, however the Shrimp aren’t. They’re still having babies, but their numbers are dwindling. Since I have the filter┬ástill running, lights on, and heater, may as well make use of a near empty tank.

The tank is overrun with snails, and copepods/water fleas (tiny bugs). Neither of these being harmful, but it’s gotten pretty unsightly. So I went to the pet shop and bought 3 Assassin snails. While I was there, my heart raced at the though of new fish. 6 tiny little neons.

The Neon Tetras immediately settled in, and started pecking at the tiny copepods on the glass. A general rule is to not feed new fish in 24 hrs as they’re normally too nervous to eat, and the food pollutes the tank. Even though I didn’t feed them I think they eat quite a bit as I no longer have these tiny little insects all over the tank. None.

Even though the tank is pretty small being only 30 litres, it’s heavily planted and provides an interesting world for these little fish. Neon Tetras are rarely the boss of their tank as they’re some of the tiniest fish you can buy, and normally introduced with much larger fish. However, in this tank, they’re the largest. They own the tank.

Video below was taken 24 hours after I first introduced them into the tank, so they may look a little shy, and slightly dull in colour.
