Thanks all!
I absolutely agree with you lousybreed, I think people use gravel so much because it has appealing properties: it's cheap to collect and therefore to buy, it is easy to clean, it can provide rooting space, it is relativelty aesthetically pleasing and it cannot harm the fish (no sharp egdes on stones etc.). However, for the fish, it's not that natural.
The tank has just had a bacteria bloom and now looks very cloudy. Im fishless cycling with ammonia and seeded filter material. I might add a picture in case any new people to the hobby who want questions answered about why their tank is cloudy stumble across it. I'll also add a few pics of the equipment and general setup, make this more into a journal of sorts.
As far as the channa goes lousybreed, I already have him! He's in one of my downstairs tanks and yesterday he came out for food for the 1st time and got a prawn. He now likes me... I give him prawns.

I have to say I dont really want to move him, the bichir, snakehead and ropefish are all getting along really well and it'll be sad to seperate them. I'll probably get a rainbow snakehead or an orangespotted snakehead for that tank. I've finally got a photo of him that is worthwile (ish), but you still can't see the proper colourings. All of the photos on this post have been taken with my phone camera thus the iffy quality. (The 2 pics of the pulchra are the linked ones underneath the other pics)
Anyway - enjoy the pics.
Anyone with any any other ideas on fish?
