Hillstream it is then!!!
Any ideas how big they get? 8O
I've been thinking about splitting up the orandas and the loaches after my recent discovery of an Oranda's full size, and was thinking of keeping the loaches together in their current tank, but if a Hillstream needs a higher water speed than a Weather, then there may be three unhappy fish and one very pleased one!!!
Soooo, if I had a smaller river styled tank for little Hillie (it is technically my fish!!!), and leave the other three, and maybe a few other fish that won't overstock the tank, in the big one maybe I can get away with keeping everything happy, assuming I can get a biger tank for the orandas!!!
MTS here we come (well, not me, it's my mum's tank!!!)....
EDIT:
I think I have his/her species nailed, I was just looking at the fish on the driftwood (algae munching) and I noticed it flicking up it's forsal fin when moving backwards and it had a red stripe running along the tip, and I was looking at a picture of a similar one last night, so I just looked again and I think the Loach is this breed:

I'm not even going to try to say the first half of the name!!!
EDIT AGAIN:
2.25 inches is the maximum size of that breed... 8O
Pretty small that... 8O
Anyway, I've just been watching it eat a bloodworm, I've never seen it do that before, it was so amazing to watch!!!
