That's because early in embryogenesis a collection of multipotential stem cells called neural crest cells migrate to the dorsal side of the developing neural tube, just below the presumptive ectoderm that will become the dorsal surface of the embryo. This is the area where the dorsal fin will...

Same here; I've never heard of a glass tank being held together with anything other than silicone.

Either that or alien invaders... :eek:

OMG, the Fishbox is being taken over by Goldfish!!! :lol

Some interesting facts about goldfish- (i) Goldfish, Carassius auratus, have bee selectively bred in captivity for at least 1,500 years. (ii) Global aquaculture produces more than 3 million tons of Carassius auratus annually. (iii) Goldfish are tetraploid, like most food crops, making them...

The slowest-growing fishes I've ever kept were Altolamprologus. The upside was that they lived a really long time.

I got 'em! :)

Amazing tank; looking forward to seeing it in person.

Cool. I figured that about the Ludwigia, but I'll be happy to have the Crypts. Thanks!
