that looks very nice

that is kinda how my baby feed cups are, but mine are the wide, short deli cups w/ a net bottom - about the only thing I could suggest would be sure if he were to get in, he can get out- I had one of the babies get into the feed cup, but was to short to get back out- lol I solved this by pointing the end of a vine so that it did not touch any of the sides, but poked down into the cup so the bugs can not get out ( I feed them roach nymph now too - dont want those lose !

) but the cham can reach up and still grab it if needed - mine are baby Jax 4 mo old, so they are about the same size as your little guy - but that looks very nice - GREAT JOB
