Yeah it's extremely hard to not try and constantly move them to get them to open up! I'll let them sit where they are now for a few weeks I'm hoping it opens up sooner then later. Yeah their mouths open sometimes and other times their completely closed!
Yea I know the feeling lol.
If you can eventually figure out what variety they are, it will be a lot easier to keep them happy. A lot of different types will like different conditions.
If they don't open up within a week or so, maybe start a new thread and someone with more zoa experience may chime in and give you some first hand advice
I haven't had much experience keeping them.
They should be fine though!
Also, nice looking frogspawn.
