Ok. Can they climb up the side of the tank? And do they eat the fish's feces?
Yes, and yes...
HOWEVER! *Yells enough to cause all the fish tanks to shake*
I've had my Ghost's for about 2 weeks now they do tend to go up and down the tank but I think it's because they are playing with their reflections in the glass. Much like your betta sometimes will play with it's reflection. I have several open spots on my tank that they could easily climb out from... so far so good. I've even watched them go to the surface but it was only to grab part of a plant and try to pull it down (Normally they fail and they comically fall and flail all the way down).
For my 10gal I purchased 12... 2 weeks later I can COUNT 8-10 then again don't bother I don't see any shells of them and Drax doesn't seem to go after them so I bet all 12 are there just I never count them right. Some hide, some are always out.
As for feeding... *Shrugs* I don't really even try, same as my mom when she feeds during the week while I'm at school. Drax watches you VERY closely when your at the tank (With his good eye too) and gobbles up anything you drop in. When feeding I do try and sink several pellets down while he's eating other pellets but if I'm not fast enough he'll then dive down and literally grab the pellets from the Shrimps hands He just ate the one my Egg Laden Shrimp (Bertha) was eating! HE STOLE FOOD FROM A MOTHER TOO BE! XD
But as I said... it's been a few weeks and most of the shrimp are still there, very glass like and healthy, so obviously their finding enough to eat on their own.
Also forgot to mention...
More fun from my mother... at first she thought the Shrimp were creepy... "They look Like Spiders!" Two weeks later... she's like. "Oh it's so fun how they grab a pellet and run off with it! I get lost watching them sometimes!"
From Creepy Spiders... to Adorable little Clowns... EVERYBODY LOVES TEH GHOSTIES!
