Which kinds of creatures (fish and reptiles) can go into a 29 gallon vivarium?

5 gallons really isn't enough space for any type of fish except maybe one small feeder mosquito fish which would probably get eaten by some animal in the tank anyway. If you want to create mixed-species terrarium, then you're essentially ruling out any sort of frog, as it will attempt to sit in the water, and some frog species do not swim well, and all frog species will leak their chemicals into the water, destroying pH levels for the fish and contaminating the water for any animal trying to drink it. In essence, you'd probably be looking at a type of arboreal lizard, most likely something such as a Green Anole, Long-Tailed Lizard, or House Gecko, which can do well in minimized space due to having a more complex set-up for a water section.

this is purely too small for a chameleon! Get a green anole or an armadillo lizard. nicely you are able to in all probability living house a million male and four lady anoles in a 29 or one male and a woman armadillo lizards. listed under are some care sheets for the two green ANOLE Housing: your 29 will living house a male and a couple of-4 women. Substrate: i prefer to advise cypress mulch or moistened coconut fiber lighting fixtures: one 8.5 inch dome fixture with a 40 watt basking bulb. additionally one dome fixture with a UVB gentle Water: modern-day a shallow dish and mist the leaves of the plant life every day. nutrients: they'll consume anole bites fruit flies wax worms crickets meal worms silk worms and phoenix worms plant life: Have many hiking limbs and plant life hide container: use a chook living house and hang it up severe for a hide area ARMADILLO LIZARD Housing: your cage will living house a male and a woman Substrate: use play sand or cage carpet lighting fixtures:use a seventy 5 watt bulb on one bring about an 8 inch dome fixture with a UVB gentle on the different water: mist another day modern-day dish nutrients: feed comparable as anoles advert an occasional mouse hide container: get one on the puppy save or great-glue some rocks to make a cave

There is no fish that would be able to survive in less then 5 gallons of water, and even if there were they'd be eaten or dragged out of the water.

If you plan to increase the amount of water I can give you some suggestions.

I am well educated on freshwater fish, most brackish water fish, fully aquatic frogs, most semi aquatic frogs, crabs, and newts. If you'd like to email me regarding them that would be fine.

Just so you know, frogs and crabs are not reptiles. they are amphibians and arthropods respectively. As long as you're using fresh water, you could have some tree frogs and green or brown anoles. They have very similar requirements as far as temperature, environment, and feeding go. The anoles are completely land land-dwelling and the frogs will use the water on occasion but mostly stay on land. Neither will eat your fish.
