Verru not eating

[ryan]

Heh guys, i am currently keeping a pair of verrus. I bought them seperately, abt 1-2 months apart. The 1st 1 that i bought is feeding well, whereas the 2nd 1 is actually not eating much, or at all. When i bought the 2nd, i actually moved them both into an air-con room, and during that period, both of them seldom ate. Anyway, abt 2 months later, i moved them back to my original room (w/o aircon), and the 1st one started feeding normally again. However, till now the 2nd one is hardly eating anything, and is already very very skinny.
What could be possible reasons for this?
And what should i do now?
Anyway, i will add in a photo of the 2 of them together, and u guys can see the size difference.

ya I know

Maybe u can elaborate more on the tank setup??

 

[ryan]

haha, yeah!
the skinny fellow has started feeding again, i was reading my notes when i noticed her moving around, next i saw the mouth moving. I stared at her for awhile, and noticed she was eating the bloodworms which i left inside the water. Anyway, also noticed she was rubbing herself against the tank n my deco. Then i looked closely at her n noticed she is actually shedding.
Anyway, finally got her to eat....yeah...
