Limnobium Laevigatum Tropica 1-2 Grow

Hey everyone 

I brought some Limnobium laevigatum Tropica 1-2 Grow recently and I have pest snails in my tank which I don’t really mind and they haven’t been any trouble. I usually keep the population down as much as possible but since adding this floating plant the snails have been destroying them as I’ve noticed their little mouths rasping on the plant leaves from underneath and while there is some new growth, they are just getting Decimated while the other plants are not being eaten.

Now I understand that there is information out there that suggests the plants are eaten once dead or dying but that isn’t the case as the f.plants are growing strong thick roots. So has anyone got any ideas??

Not really I will try and up load some pictures later to help me explain what’s going on. I did have the plants penned in with thread but when I noticed them going south I removed it and let them be free. Now they seem to be drawn to the outlet of the filter box. Occasionally I will find one caught up submerged and dancing around with the flow.

I can't comment on the snails factor but, any time I've kept these plants, that's *exactly* how they become, then seem to get 'singed' by the light and deteriorate further / die.

A lot of floating plants don't like water dripping on their leaves. Years ago I used to have a species of Salvinia and that all died off during a heatwave when there was a lot of condensation under the lid.There's a thread about it on here somewhere.
One plants that copes well with condensation is water sprite, which is what I have in my main tank now.



Found it! Read the posts by Natalia re the salvinia. It may also apply to frogbit.

I believe duckweed is a bit more robust but I’ve not tried it in a closed top tank before personally. Brasilia pennywort can also be grown floating, I imagine it might fare better too.

Hi @LeakysLab

I realize that this is an old(ish) thread. But I'd be interested in knowing what species of snail you have in your tank. Or, are they history now? And how is the Amazon Frogbit? Did it survive?
