I have 2 Nikita tincs, that are very active and fat. Both of them climb the glass; one of them climbs to the top most leaf of their philodendron in a 10 gallon tank and jumps up, smashing into the tank top and falling back down, is this ok, or is it a sign of stress? I thought at first that he was after a food item, but I don't see anything up there. I know it's recommended to put 2 in a 20 gallon, so I set one up 2 days ago, but should I wait before adding them (didn't know if it was like setting up a tank and letting it cycle)? The vivarium they're in now has been set up for years, with periods of time with nothing living in it, but did have another pdf living in it a few months ago. Another question I have is I found mites in the ff culture I've been feeding and I'm worried that they will harm my frogs, what should I do? I got rid of the culture, but I'm sure some mites were dumped into the tank. Any information would be most welcome.
