Title: virile crayfish (Orconectes virilis)
Post by: Corwin on September 01, 2008, 10:30:53 PM
when i was camping i caught a couple of these guys, one 4 inchers (tl) and one 6 incher (tl). and a bunch of smaller ones too.

i was wondering if it is possible to keep them in the home aquaria, most info i can find online doesn't say much except that they are an invasive species, i cant find water requirement, or size, or much of anything on this particular species. i know they are these species, because there are only 3 known species here, and these big ones look exactly like the pics provided (i therefore assumed the small ones were the same species too).

I'm going to assume that you didn't bring any home with you.

I feel certain that the crayfish can be kept in an aquarium and that in general all the same rules apply for this species as does for any other FW crayfish.

You need to find out what the adult size is for this crayfish. Keep searching.

Water Requirements: Same as the water you caught it in.

I know that's not very helpful but if you can't find more information I will search later tonight and see if I can find anything that will be helpful to you.

we did not bring back any -live- ones this time (they make good eating after-all), but the stream i found them in was only an hours drive away (might go next weekend if i can get the right info and can keep them.

here is what i found from a couple sites while at work (shh, don't tell me boss):

1 cray per 10 gallon tank
10-12cm lenght
2-4 year lifetime, usually die within first 2 years, after having one brood, 4 is exceptional
extremely aggressive (yike tell me about it, didnt have to read it to believe it!)
likes to hide in rockwork.
young have orange tips on claws (so the small ones we saw were young) and the defining trait of the species is red lines between the tail scale thingies

the stream was lukewarm, and currently running silty with all the rain (literally could not see 1" beneath the surface, which made it even more fun to fish XD), from past experience it usually runs completely clear. there are almost no plants in the stream itself (but many on the edges that likely have hideout roots in the water) and a lot of rockwork and mud.

i have 2 empty 10 gallons (snails excepted) right now.
