Ant colony not growing

[campobarairversa]

I own a Camponotus colony and they have been stuck between 10-20 workers for 2 months. Any advice would be appreciated.

The species you own (Camponotus) is a slow growing species which means that it is OK if they stop growing for a while. If you live in a place where it is winter or cold right now, you don't have to worry because they are in hibernation. If you live in a warmer climate or in summer, check that the queen is still laying eggs. Also, could you send a picture of your colony so that I could help you find a better solution?

You can add heating underneath their test tube or nest.
Also, is the queen still laying eggs? If she is, just feed them more and they should grow better.
With my experience of camponotus, it is best to feed her honey or sugar water, and small insects for protein.
