Fertilizer of any kind in an amphibian tank is an absolute no. Amphibs absorb just about everything through their skin, so it will kill them quick. You will basically be relying on frog waste to fertilize your tank. Don't worry, it will be enough. Plenty of people have done it. As for ventilation, with it only being 20 gallons I would say having a screen top will be all the ventilation you need. You can get plants at blackjungle. I have never tried to buy fungi of any kind, so I can't tell you where to get them. I have found that they do a fine job of showing up all by themselves :)

Hi, you can always go down to the "search" at the bottom of this page and look up answers to most if not all of your question =)

Also try, http://www.tropiflora.com/creport/cr15-3/p0.html, they have pretty cool stuff too =)

Unless your tank is in a cold area, I don't think the heating pads will be necessary. Generally the lights generate enough heat, and I think that using a heat pad under glass that contains water *might* cause the glass to crack.

Unless the water part is only one or one and a half inches tall with some water friendly wooden branch in it for safety reasons, any dart frog would probably drown in the water. Dart frogs can not swim. I own one and it can't swim at all. They need shallow streams that are only one and a half inches deep (two inches for the bigger species) at the most. Also, they might want a branch in the water in case they have trouble and need to get out of the water for safety reasons. I've seen pics of other people's tanks on this forum and on the internet and they have the following for water sources: a waterfall that turns into a shallow water stream, a small to medium sized reptile rock dish (I have one of these for my dart frog, Rain), or a small water wading area. I have seen pics of tanks where the water is four or more inches deep and never see any of the frogs in the water in any of the pics. Probably because they would not feel safe in such deep water. Somebody even had the cocohut in the deep water part where one-third of the hut was in the water. I doubt that the frog could use the cocohut at all. Remember, dart frogs come from the rainforest where there's mostly soil, trees, plants, and small puddles of water on the ground among the leaves. Since you did use silicone on the water part, I would suggest a tree frog. They can stand three to four inches of water, swim a little bit, like tanks that are on the tall side (most of the dart frog tanks I've seen in the pics were the ones that were on the long side), and would get along good with pitcher plants (I saw one sitting in a pitcher plant at one of the spring festivals that I went to and it was able to safely get out of the plant). I hope you give this advice some consideration.

Thank you for all the help I think you are right alexis a white tree frog would probably work better plus he is sticky and can climb all around the tank and not drown in my deep pond.

Do not heat the tank!! Room temperature is enough. If you are going with a poison dart frog then you need a glass lid, no ventilation. Absolutely no fertilizers or chemicals of any kind. Wash off all plants completely bare root before putting in the tank. Definitely stick to flourescent lighting since it is the right kind for the plants and will not overheat the tank like an incandescent bulb will. Find a good forum like dendroboard to talk about the care of the frog. They will help you out a lot. Get a thermometer and hygrometer for the tank. Good luck!
