Hi Marc,
I figured out what you mean

and i would to say you the same for the info you gave me on the backgrounds.
The problem with plastic backgrounds is that wood-eating plecos chew on them and scrape off the colour and then all their beauty is lost...But i guess there is no such problem with auchenipterids,right?
My Echinodorus were also eaten by L18's
So,i think you know exactly how annoying it is to have your Echinodorus damaged.What can be more annoying is to have an Echinodorus in a tank with plecos for months without any of them damaging it and then after many months or even a year that the Echinodorus has grown huge and beatifull and you think is ready to flower the plecos start eating it.This has been my experience with an Echinodorus bleheri that my L190 decided to ruin after almost a year(10 and a half months,yes i was counting them as i was impressed by the fact it wasnt eaten)by eating its roots(not exactly the roots but the place from were roots were coming from).My experience with other Echinodorus has been about the same although they were eaten after only some weeks of introduction and so i was less annoyed.
The only good experience i have with Echinodorus is with 4 Echinodorus osiris growing floating in one of my tanks.They are growing like that for 1,5year now and although they never throw huge leaves,they have quite a few 10-15cm leaves on them.When i first got them i planted one of them and left the others floating until i find somewhere to plant them.After some days the planted one had holes on its leaves from the plecos while the ones that were floating were intact.So i let it float too.
Anyway,i hope yours flower soon
P.s.Have you ever been in Greece?
