Good grief! In the first place, the Dendroabtes are diurnal and don't call at night. If you sleep during the day, the refrigerator going on an off is louder than the loudest leukomelas. In the second place, those of us who raise them are always in a quandary about whether we have even heard them, or what we have heard is a male calling from the pumilio/imitaor/whatever tank, or just the refrigerator squeeking. We sometimes spend many hours trying to sex the frogs by observing a male calling. These are not chorus frogs. They will not serenade you like an incessant Wagnerian opera.
The annoyance may come with the exacting care and specifics they require, such as raising tons of fruit flies, springtails and crickets to feed them, keeping specific humidity, temperatures, misting and building inventive terrariums to house them with a lot of tropical plants you need to appreciate, as well. Pumilios aren't what you want to start out with, and that's not because they will bother your sleep with noise. It's becaue you have to learn a hell of a lot and take a lot of time and effort to build your first vivarium for your first dart frogs. It is not about worrying whether they might bother your sleep with noise. If you are willing to pay from $125.00 to $150.00 plus shipping, per froglet the size of your small fingernail, the least of your worries is whether it will ever annoy you by making too much noise.
