So I got a new reptile tank I believe it's a 55 gallon, maybe bigger, I picked it up with the stand for 20 bucks, already tested it and it holds water. So here is the project plan. I'm using a lot of styrafome to keep the tank weight down, I'm thinking of building of it to have about 3 or 4 male bettas, all in separate 2 or 3 gallon pools, all connected by small streams. The center of the tank is gonna me more of a terrarium setup that is elevated above the water levels of the betta areas. A filter will draw the water, spit it out on some rocks like a stream or waterfall, that water will go to the first betta pool, then over flow to the second, third, and fourth tank, then finally return to the lowest level for the filter and heater in the back. Any thoughts or concerns? I know I have to keep the weight down since a reptile tank doesn't hold heavy weights very well. But I'm thinking I won't have more then 20 to 25 gallons of real water in it, the top is gonna be some rocks, maybe extra substrate, and moss. May possible have to alter the water flow though, I'm only using the filters to basically push the water, I'd imagine I'll need to individually clean each mini tank so I'll build them with access in mind, possibly may even add a air pump. Obviously I will add, the bettas will not have access to each other or be able to see each other. Just though it would be cool, a multi beta tank with a larger flowing water system. Also, before I get yelled at, yes I'm avare that it floats so I need to anchor it, yes the edges of the Betts tanks will be made of styrafoam, bull I'll be painting it then building walls out of stones or something.
