I've got 2 in my 20G, they are about 4" long had them over a year.

1. Filter size/feeding habits, #of plants etc.
2. Had a major snail problem, they don't do squat for snails
3. not demanding at all, I bought them because I was breeding Kribs in the
20G and I needed something that was nocturnal and would clean the food
scraps for me becuase the kribs were stressing out all cories I had in
the tank.
4. 5 in a crowded 10G when I was kid. I would get at least 3, but
remember they hide during the day time. Nobody will know they are
there but you and them.

1. how much do they add to the bioload of a tank?

2. snail eaters? not a snail problem, but if it were to become one,
dont' want to have to get another to fix it....

3. very demanding or not?

4. gregarious??? meaning it plays hard???

5. recommended tank size is unknown, what's the smallest you've put 1
or 2 in??

Just curious, set up a 10 for a friend and looking for tankmates...
