Iwagumi landscapes are more for nano fish and shrimp .Not sure how it would cope with Axies .I used to do Nano Iwagumi landscapes in 13ltr and smaller tanks
it'd be cool to see if it'd be okay for axies but i'd worry about the string that needs to be wrapped around the weeping willow mossto get it to stay on the sumatra wood till it is able to root itself and also sumatra wood tends to have jaggy bits so it'd need a lot of sanding but you could always use different wood type .
landscape rock and dragon stone which is common in this scaping are also rough with jagged bits (I have loads of this stuff but i'm too scared to use it in the axie tank) so perhaps go for giant river stone or wood rock which is more smoother wood rock being a bit rough but normally less jaggy.
your substrate is also going to have to be plant substrate to keep it healthy for a bottom base then add sand on top
for plants hairgrass ,Fissidens and Java moss buuuut
I've not seen a freshwater iwagumi tank yet ...i'd love to know what grass like plant that can live in cold water could be though .The only moss i've seen be okay in cold water was the mossballs.
you could flatten out moss balls ,I used to make little grass gardens in my nano tanks by opening the moss balls flat but they never really stuck down well without a rock ontop and gathered muck easily D:
I miss doing iwagumi so it'd be great if we could find freshwater alternatives! if anyone is good with freshie type plants that could help ?
