ie.
red finned shark
red tailed black shark
ruby shark

red-finned shark, ruby shark and rainbow shark are all common names for the same fish as far as I know.

nope there all different.

red tails are black with a red tail.
red finned are a dark grey with reddish fins
ruby sharks are dark grey with more orangy type fins.

not sure on rainbows haven't seen them.

I'm not having neon tetras, i just bought 6 and 5 of them died, I'm not particularly keen on them anyway.

I'ved hacketfish in my book but I was put off by there picture although it doesn't seem a too good one, any links to some pictures of them? would a number of them be ok together?

I never said red-tailed shark and red-finned shark are the same. The red-tail has (obviously) a red tail, while the red-finned one has all of it's fins coloured red. Rainbow shark is another name for it.

And I'm pretty sure ruby shark is another name for red-finned and rainbow shark too. A healthy rainbow/ruby/red-finned shark should be very dark, almost black, but they are a light to dark grey as juveniles I have had one in my 21 gal for years, he's happy but he does need a place to hide and will defend it ferociously I'd go with the hatchetfish idea to go with the crayfish, they are quite cool and they're less likely to become lunch than any bottom dwellers

EDIT: Phew, too many quotations

Hatchetfish and giant danios might work, since they are both top dwellers and are too fast/big to be caught and eaten.

yer, i think i'll look into them, the picture in the book had been cropped strangely!!

It all depends on what size tank I will get as my center piece, if i get a 5ft oer a 4ft I would happily leave the cray fish as a species tank!! maybe put live bearer fry in there.
