I don't!!... Just a photographer... and a bad one at that!!
Anyways, like Vince said... check with Toyin (Rohoboth Aquatics). That will be your best bet! I beleive he does have Congicus in stock now. GL!
I just now found out that you where looking for a delhezi and FlammingWoodChuck was looking for a Congicus.
And my comment about tank size was primarily pointed towards FlammingWoodChuck, because a Congicus get 97 cm and a Delhezi get's 40 cm or so. So I think you will be quite good with your 75 gallon for now and a around 120 gallon in the future.
And you FlammingWoodChuck, where do you wanna keep you full grown (almost a meter long) Congicus in?
P. endlicheri congicus do grow large in size,,, but it will take some time before then. FlammingWoodChuck, should have more than enough time in-between then, to upgrade to another tank, if he decides to??
But,,, if he (or ANYBODY else?) has a Congicus that outgrows their tank, and needs to move them... I can help out by letting me buy them from you. 18"+ and UP only!
