I have a 50 litre planted tank that is set up and running. CO2 is set up, but not currently being used. Used to have shrimps in there, but the room will have a large discus tank in the near future, so shrimps (crs at least) are no longer reasonable due to the room's temperature.
So, I'm planning ahead and thinking I would like to have a large school of nanofish, 2cm max. I'm not familiar with fish this small, so I'm looking for suggestions. These are my requirements:
If you think any of these requirements are unreasonable please speak up and we can have a chat about it. I could convince you it is actually reasonable, or you might convince me to change my mind about it.
So, I'm planning ahead and thinking I would like to have a large school of nanofish, 2cm max. I'm not familiar with fish this small, so I'm looking for suggestions. These are my requirements:
- They have to be schooling. It is not a strict requirement, but I very much prefer a school to a shoal.
- They have to be active. The tank is right next to my work desk, and I would appreciate when I glance over to it not to have specks hovering in the water not doing much.
- I would prefer them to be adaptable. I can deal with changing water parameters, ultrasoft water and so on, but I'd appreciate being able to avoid it and just use tap water.
- Easy to breed would be an appreciated bonus. By this I mean that I would like to see an new fish appear in the tank every now and then. The tank is well planted and well mature, so there is a rich microfauna and there are plenty of hiding spots for fry. This being a species tank should help in this sense.
- Don't require live food. This is a firm requirement. Unfortunately live food here is available only if you culture it yourself, and I'm not ready for this yet. Even frozen food isn't popular here (go figure...), so they must be fine to eat prepared food.
- Non-jumpers, or at least low risk of jumping. The tank is open and cannot be closed due to plants growing in there which have grown well past the tank edge. Also I intend to add emersed plants and make it into a small riparium. No floating plants for the moment, but they can be an option.
