Okay, I've got some baby D. Ventrimaculatus (FG). They are two months out of the water and they are very small. I already have the tank very well seeded with springtails and would like to include some isopods. What type do you recommend for baby thumbnails? I would like to add as much variety to their diet as I can. I put in the dropsophilia melanogaster fruit flies but I don't think I've actually seen the frogs eat them. I could be wront though. I've got an icky growing piece of bannana in there which is now home to many crawling things. Ewww....
