I currently use strictly 10 gallon tanks right now. At one point, before I had room to set up the 10's, I was using plastic tubs. They worked out quite well, and they can be broken down, stacked together, and moved out of the way when you're not using them. If you run them with sponge filters, it makes it really easy to set them up quickly.
Here's what they looked like:
You have to be careful if you're using these though. You need to make sure the heater doesn't touch the plastic. For that reason, I used the preset Tetra submersible heaters. They have rubber on each end that keeps the heating element off the plastic. I still have them, but haven't used them to raise fry for quite some time. I now use them mainly to put rocks in when I'm mucking about in the tank, or stripping a female.
In order to get them to 2", especially with
Ps. demasoni, you will be able to start them in a 10, but as they grow you will need to move them into progressively larger tanks. Quite possibly this means dedicating a 4' tank (because of their aggressive nature) to growing them out. A 33 or 40 gallon long tank would be perfect for this.
PS. I saw on another forum that you live in the same city as me. Feel free to drop me a PM if you want to come see how I do things. I don't have much, but I make it work hard for me.
