Marble Crayfish- Marmorkrebs

[keith_r]

just got my first marm last week.. it was a freebie that came with my scud order!
we'll see how it does - it's in a 55 gal tank with some rosy red fry, 1 adult rosy red male (protecting some eggs) snails, scuds and daphnia

watch the snails....they eat eggs....cray may eat them too.

the male does a pretty good job of keeping the snails off,, i help out occasionally.. the cray can't walk upside down on the pot so they're safe from her
i'm hoping to pick up a 120gal glass tank in the next few days.. just gotta figure out what i'm going to do with it..

Too bad you are not closer. I have too many tanks taking up space in the garage.
IF the snails get out of hand, put a peice of leaf lettuce on the bottom with a rock. Snails will gravitate to it, lift it out after about 45 minutes to an hour and shake the snails off to the perch. Snails can get out of hand.

they're starting to get out of control.. just read that the marms will eat them so thats a good thing.. i just saw one of my papershell crays eating a snail in on of the other tanks..

Anyone eat these things yet? How big do they get? Pictures?

[keith_r]

i don't think i'll eat them, but use the small ones as feed for my yp/bg or trout when i go that way..to grow out crays, you'll need lots of room.. i put a few dozen in a 110 gallon tank my first year, after 6 months there were 2 left..
i've got probably 2 dozen in an 8' kiddie pool, and could probably do a bunch more in there, but thats where i want to put my fish to grow..

I had 3 in an outdoor system which is being taken down... I brought them inside into 3x10 gallon tanks and 2 of 3 have berried in 3-4 days. I guess the temperature change triggered something.

what's the temp in the aquarium?
mine is at 68/69 pretty steady right now, but i could turn the heat up.. mine is only 1.5" long or so.. but it's antennae are a whole lot longer than the papershell crays!

[bcotton]

room temperature, i am not heating the aquariums at all... We keep the house around 72-74 so the water is probably range 66-70 degrees.. the temp outside had dropped to the 50s before the move.
