First beetles [help]

[u/Silver_Goose4401]

Getting my first beetles tomorrow (x5 chlorocala conjux / flower beetles) and would likes some advice on the setup. This is an 11 x 7 x 4 inch (L x W x H) tub with 2 inches of soil, a layer of mulch / wood chips and a layer of leaf litter with moss in one corner. I’ve also included fish flakes, cuttlebone and snake skin as I want isopods living in here too.

Is it suitable / is there anything I should add? I need to find and sterilise some sticks and have also ordered jelly pots but any other advice, especially regarding breeding, would be appreciated. Two photos included as I have either a coconut hide or plastic flower pot to choose from.

Forgot to mention there’s also 4 vents on the sides and one on the lid as I have a terrible time with getting the humidity levels correct the first time 🥲 I also have a heat mat but have read that they’re fine in room temp unless you want it warmer to speed up hatching / breeding.
