You just made the place!

What are your questions?
Last night i found out is a clawed, not a dwarf

! his toes gave him away..
Hes still pretty small, about an inch long, ill try to measure him, its nose to vent right? how big will he get and how fast? based on size, how old is he now?
Ive been feeding him TetraMin Tropical Granules, thier a sinking food i bought for when i get my cories. Ive read that theyll eat almost anything, and love bloodworms, but all i have are freeze dried, and ive read that that might impact thier bowels and give them bloating? Plus, ive been feeding him with a dropper, he loves it!, and i just cant get bloodworms to get in the syringe!
Right now, hes in a gallon fishbowl, as a QT before i put him in the 2.5.
Hes got a pot and some rocks, and as far as i can tell, hes not sick in any way, ive read a few articles about frog diseases, though id like some tips to look for? any signs?
how often should i be changing his gallon QT? Daily?
And the rocks i have in the tank are about the wieght of a marble, but they are smooth river rocks, washed many times over, will they be okay for him? ive read that when they move around the rocks, which he does alot, if the rock is too big, it could fall on them and cause them to not get air and drown...how big is to big?
Ill probably have many more questions, and here are the first two pictures i took of him/her..im uploading more now.. maybe you can tell me if its a boy or a girl?
