Hi D.J, Nice looking tank. I don't know if your missing anything there. It looks great in the pic. If anything I'd ask just two questions. Is there some waterfeature there? I don't see one and I like them in tanks, but thats just me. Second, is an 18 gallons tank big enough for 4 vents? What did Mark say about that? I'm wondering because In have a 15 gallons high (just a little smaller) that I had planed for 4 fantasticus, and after watching the first two in there I wonder if there is enough territory for four frogs. Back on the positive side I like those moss covered sticks. You must have collected those yourself.
