Can a 7.5x12 inch faunarium house any reptile or insect long-term?

A 29L is a good sized enclosure for this species of tree frog. Juvenile frogs are much more active than adults. As your frog matures, it will "settle down" and spend more time on the ground. You can still use branches and perches to make use of the vertical space. You can keep two in the tank if you choose as long as there isn't a significant size difference. Different species cannot be kept together though. They do not need a night light. They do best with a 12 hours on/off light cycle.

An appropriately sized plastic carrier would retain heat much more effectively. Pad the carrier with towels for protection. If you are traveling any distance, consider wrapping a hand warmer in a towel and placing it in the bottom to provide heat.

Hi there! We have a Crested Gecko and have so much fun with him! Don’t worry, they are a great starter reptile and are pretty easy to keep. In the winter we use a red light to keep the tank warmer, but not a specific heat lamp. This keeps the tank warm enough without getting too hot. Also very important is the humidity of the tank. Keeping it spritzed several times a day is necessary. We started with a tank your size and it probably would have been just fine long term, but we ended up purchasing a larger tank because we wanted a different look. Best of luck and have fun with your crestie! Thank you for using Pet Coach.

The Cowfish, or Longhorned Boxfish, is a marine species that should be kept only by experienced aquarists. When stressed, they can release toxins into the water which may harm tank mates. Pacman frogs, leopard geckos, corn snakes or bearded dragons are all easy to keep.

Ideally, the UVB light source should run the entire length of the tank. A thermometer/hygrometer should be on each end of the tank to confirm cool and warm sides. Use a digital thermometer to verify temps. Those little ones you have can be inaccurate. Provide a hide on both sides as well. Personally, I would remove the fake grass as it has the potential to cause eye injuries. Your tank looks good otherwise.

Corn snakes can grow to as long as 5 feet. On average, they grow to 3-4 feet. A 10 gallon tank is too small. At minimum, a 20 gallon enclosure is recommended. A temp range of 75F-85F is best. They do not "need" a UVB light source but seem to be healthier with one. At 2 years of age, it should be eating adult mice. If it can't, feed whatever you can to get it back into a positive plane of nutrition so it can grow properly. Consider an exam with your veterinarian or an experienced herp vet to diagnose and treat any pre exiting conditions. Submit a stool sample to diagnose intestinal parasites.

An adult crested gecko should be housed in a 20-gallon tank with screen top. Larger tanks will allow for better displays. In areas with moderate to high relative humidity, crested geckos will fare well in screen cages.
