Why can't I keep floating plants alive?

Yeah I'm currently employing the suction cups and fish line method. Too bad my honey gourami have munched their way through all the roots!

That's a new idea on me. Yes, I found Gouramis have that habit too!

Thanks @Caol Ila for starting this thread. I have only just added floating plants to mine and keep putting them back into the flow when they get stuck just out of it. I didnt know they prefer it out of high flow. I will probably make a holding section for them out of sucker cups and a long piece of thread

I had a full sized water lettuce (not dwarf) that my Bosemani rainbow fish eat/destroyed in one night. Eat the leaves and everything.

My three boy Guppies must be vegetarians as they chewed through all 12 water Lettuce in a matter of days..
