I have a couple pest snails, but really just the two cherries. Would like to get more cherries at some point but need to stabilize this setup first. I was told KH has to be at least 3 or they won't be able to molt. There's so much conflicting information! I've been thinking at this point, I should just pot my swords in there and keep the bottom of the tank bare so I'm not fighting the substrate.
Is it really okay to keep going with the way it is; this won't harm them?
