Java fern and some types of crypt. they eat everything in site otherwise.
I had some anubias and while they didn't eat the older leaves the newer ones
never had a chance. I feed mine red leaf lettuce alot - they seem to really
enjoy veggies with red in them. An I hae to say it helps bring the red out
in their colour too.
