You might be right Yucca,but most cave animals eats very little.

Wow that is realy a different crayfish.How come you think they would be hard to keep Yucca? The only problem that seams obvius to me would maybe be sensitivity to high temperatures .

All natural sponges I have seen for sale here in sweden have had the same colour as the one pictured here which are chemicaly treated to get that pale colour .When I have been on holiday in greece I have seen natural colored ones for sale they are much darker in colour and would look much more ...

What have worked best for me with dwarf crays is giving the pregnant females their own little tanks with lots of plants it also makes a good nursery for the fry.It does not even have be any filter with such a small bio load.Or keeping them in pairs in small tanks and remowing the male
after spawning.

How is the breeding progressing ?

Oak leaf will increase the general production of micro organism in the tank ,but in a highly populated tank the subadults and adults can still "ower graze" what the leavs produce.

I have seen some good results in a friends tank but have yet to try it my self. It is a pitty they don´t make the ...

I think the reason for the decline in surviving shrimp usualy is due to "ower grazing" by the adult shrimps ,the shimp fry is probably much more dependant on the "natural" food produced in the thank than adult
shrimp.If you have a large population of adults they will probably also

By the way...I know *for a fact* that your males are not sterile, as the females would not be carrying around unfertilized eggs for any appreciable amount of time. Plus, those eggs would turn a different color (different from ...

that is not completely true. There are many examples where inbreeding has no obvious negative results. 'The only important thing is the genes. Inbreeding only gives a individuum a higher chance of having some defects in both copies of its genes. If one selects for these genes to be ok, when ...

I have had C.paztuarensis for maybe six months now and had both problem and sucses I started with six females carrying the orange gene
and tree orange males ,of thouse I have all males left but only one female

Any special reason you did not keep the patzuarensis? I had gotten the impression that maybe shufeldtii is more shy in behavior?

What are difference between C.patzuarensis and C.shufeldtii when it comes to behavor?

Thanks for the information
