multiple fish questions!

[virus]

hey,
first off i just got two new fishies a baby blue crayfish, and a gourami, and i have not had experiance with gouramis or inverts, so is there any special care to take with them?

Secound, that my gourami keeps by the back right corner of the tank, its a 29 gal with 6 danios and he just sits in the corner of tries to fit in the middle of my filter and heater in the back, the crayfish has this small 3 inch tall thingy that has 2 holes on the right side of it and all he does is sit in there. is that also normal,

and last im getting some kribs in another 29 (2 pair) and wanted to know if a blue crayfish would do nice

and also how hardy are kribs? casue that would make my day

Crayfish have a tendency to catch/eat fish at night when all the other fishies sleep.
most will say it should be in a species only tank.. I would either get it a small 10gal tank or return it

Your cute little cray fish will grow up fast and it is best it live by itself. My blue crayfish lives in a 10 gal hex with things to climb, although one needs to be careful, because they will walk out of their tanks

For the kribs, try 1 male to 3 females.

any more advice?

Put the crayfish in its own tank.

you say that your gourami hides in the corner does it at least come out to eat? becuase mine does the same thing and i have had him for a little under a year so i assume it is normal
