he keeps climbing out of the water on the ledge
Froogy, I am more experienced with adfs. I know you realize the 2g tank is too small and are doing frequent water changes but you may have to do them even more often. Again, not an acf expert but I know when adfs try to climb out of the water, its very possibly ammonia poisoning. So that's why you should increase the water change frequency. Do you have an ammonia tester?
Can't comment on the injury, but I hope for the best!
