Cheers buddy, I'm thinking of red/brown Crypts in the rear corner, everything in that corner doesn't grow for some reason, most probably a lack of light, the C.willisii I bought has an average height of 4Cm, so I think it could actually be C.parva, the C.bullosa is growing out and not up. What are Spice Rasbora's I had a google and couldn't find anything? I'd love some Galaxy Rasbora's, but knowing Trowell, they're probably £5 each!
