I wanted to start a new thread for this because it is kind of a new problem/subject... I hope that is okay... OH NO! I may have found at least part of the problem!!! There is yellow mold, that looks almost exactly the same color as the wood on my wood jungle gym in the tank. I have looked at everything every day to make sure nothing is molding, but it is moling on the underneath parts and it wasn't until I was picking up toys at the base of the crab tank stand and I happened to look up that I saw it. At first I thought the crabs had torn up the wood, but then I looked again and it is MOLD!!! It's a no brainer that the jungle gym comes out but then what? I have molters down, a jumbo pp and a med straw at the very least!!! It was on the sand side of the tank, but now I am worried about my FB side too since it always seems more humid! The jumbo pp is on the sand side of the tank, we looked for him from the underneath side of the tank about a month ago. Please, any advice would be great. I don't want to freak about this and do something I will regret!!! Thanks in advance!!!
