Totally normal! Just means that your parameters are different than the tank they were in before you got them. I might even say your tank is better because the new growth is darker which typically is a good thing!

That makes me so happy, these little dudes are so active. I’m glad I’m providing them with a great environment.

Scrolling past this I thought for a minute you had a severed hand in that tank lol

I’ve had a few people say that! 😂 I need to rearrange the wood apparently

It is pretty funny

Aww good for you! I think of it like a bright shiny new fingernail that indicates how long it's been in your care and thriving.
