hmmm thats the other part of the dilemma. i toyed with growing an anubia on top of it but with the wood being so big i thought the anubia may be a bit too close to the light as i have read that they like a shady area of the tank. and if i grow moss on it would it spoil it.
anda good point there stoneagedinosaur i have now added a 3rd answer
well i was suggested it for my 10 litre and it has no co2 and is growing well but i am using tpn+ and easycarbo (but the latter is no benefit to the riccia as it hates the stuff but still growing with me dosing it)
hmmm thats thrown a spanner in the works ( but in a good way) i like the look of that fern , so much nicer looking than java fern . is it easy to grow?
