Yes- ordinary viv temps are usually too high for them. I don't want to be a downer, but they really do best outside- whether in an enclosed area or just loose around a pond.As has been said, they need a reatively large tank, some cover and plenty of food. the adults don't need too much water, but the temps must be relatively cool. Personally, I wouldn't bother, and they are pretty much terrestrial at this time of the year anyway.
It's always interesting to hear about someone's 'hands-on' experience. :2thumb: How do you deal with the temperature issue?I know this is years old. This is if anyone searches for info and comes across this. Now I’m new to reptiles but have been keeping amphibs for twelve years including common frogs one of mine is nearly nine. This info is based on my experience completely. If you have the time then get tadpoles and rear them into froglets, then keep between three to five and let the rest go so you are doing your part while benefiting to. I feed them on fruit flies, spring tails and small crickets. I feed them twice a day and once in the night (10pm-12am). gave them a 2% UV light and openly planted terrarium which was sprayed once in the morning and in the night (just before feeding) if you can't be bother do this for a good 2 years then get some from your or somewhere you know where there is a large population of frogs and its legal. If you do this then get them between July-august as they aren’t breeding and are not trying to hibernate/get ready to. Before you get your frog though you need a set up. I generally think a 60cm, 30cm, 45cm is enough room for at least five adults. You can just use coco nut fibre. i how every use coco nut fibre, play sand, dry shredded grass, dry sphagnum moss, dried grass roots and oak/beach leaves with the odd pebble somewhere. It is important from them to have a substrate that they can dig in as they will make dips or even tunnels in the case of the males. i then place the logs/rock's in. i found they like to be able to get up high and also young ones like to climb branches. Then plant the cage with live plants. I then water log the soil a month be for i get the frogs and place a 5% uv bulb to get the plants to grow. The temp needs to be between 18C-25C for them to be most active. Once you get the frogs before i put them in i water log the soil again. The reason i do this is because when in a new environment they feel most safe near water. The deepest part of water should not exceed 5cm. this means the frog can explore its home knowing if it feels scared it can fly in to the water. Until the water evaporates i only put the food in and that’s the only contact I have with the frogs. After the water is gone I then spend time around the cage at least 3 times for 5mins each a day. After about the week i find the frogs don't panic whenever they see me. i then spend time opening and closing the cage until the wont go for their bolt holes. i then will feed them and leave the cage open and watch them eat. And then if you want you can leave it at that or continue till they will take food from your hand or even be happily handled (use damp gloves or you can damage their skin) i got one female that will sit on the bed while i do work or just chilling. And one group i keep the lid off when I’m in the room. However if anyone get snakes or partially birds out near them then lock the frogs up as they will panic and if they get out in a panic they will damage them self’s in a blind panic. They will bask if given a UV light. My groups head up as high as they can and bask for a good hour so in my opinion they need it. i give them calcium dust twice a week and feed them five times a week. They get black/brown crickets, locust, meal worms, super worms (only for the adults), earth worms, house flies, wax worms and dubias. Once a month the adults get a pinki each as a treat. There will be people that disagree with me and that’s fine. This is what I found the most successful. In the nine years I have kept common frogs. I only have had two deaths. One got really bad worms and another just fell over and died with no obvious cause though that was about three years ago. Still got my first ever one. Once tamed down and given the right conditions they are in my opinion the best frog. Active in the day, social, have lots of different personalities, various colour forms (black, yellow, green, greyish, chocolate brown, Patten less, spotty, stripy, blotchy and I even have one with reddish pigment), easy to keep and can be really tame. Hope this helps anyone that comes across this.
