First of all, congrats on your new tank and your newfound interest in paludariums!!
I guess what I want to do is have it more of a rainforest type atmosphere or jungle but with also a lake type in the middle, aboue 10 inches deep and circular where goldfish will be in newts can crwal in (or whatevr type atmospher I make...
But I want an atmosphere wheere I can have like mudskippers frogs lizards turtle (since mine is very very small now) but I am wonering if my anole would fit in the same enviroment as a newt and stuff, but basically i need help on constructing such a thing
Well, my two cents are: one, mudskippers are brackish water and prefer a 3-4 foot (or MORE) long tank, and while I don't know how long your 150 gallon is, I don't think it would be that long (correct me if I'm wrong). Also, mudskippers prefer a mud flat or mangrove swamp environment, and probably wouldn't handle a jungle setting.
Some info on mudskippers: http://members.ozemail.com.au/~thebobo/mudaqu.htm
Also, the salt in the water that is needed by mudskippers would kill a lot of plants, and while very hardy, goldfish really aren't brackish water fish.
Which brings me to another point:
goldfish get very big (half a foot for some varieties, more for others-believe me, I know this) and are very messy fish, needing at least 10 gallons swimming space each, and also many fancy varieties havevery delicate bubbles or other sorts of deformities that could cause them to be badly injured on a sharp object, like a stick, or something. A very good filter is also required for goldfish.
So, I would suggest a betta or some tetras for your setup. However, that brings us to your turtle. What species is it? Look it up on the web or post a pic of it here in the forums if you don't know what kind it is. It could, however, be the sort that tends to go for small fish, so if it is, I suggest leaving out the fish and having some newts instead. Also you might research how big your turtle will get. (I also have an aquatic turtle-- they rock
it's about the size of a quarter, very cute--red eared slider, trachemys scripta elegans) This will impact the size the pond will be.
Now, for your lizards--I'm no expert here, I admit--the fish probably won't be bothered as long as the lizards are well fed. You'll want a basking light for them as well as some plant cover I imagine, perhaps some driftwood for them to climb on... so that pretty much takes care of the jungle...(hey, why not ask Zurp to draw up one of his illustrations for you?
And one last thing--I would use dividers if I were you, sealed with aquarium epoxy, to separate land from pond...otherwise your soil'll be too wet and your plants might rot.
Sorry for the long post!!
