#1. Hygrophila corymbosa

#2 I'm not totally sure what to make of that because of the picture quality, but I think it might be Bolbitis heteroclita. Not aquatic.

#3 It appears to be a Selaginella species, like in the link that follows. Not aquatic.

#4 Rotala rotundifolia.

#5 A non-aquatic Alternanthera.

 

NON AQUATIC !!! HAHAHA does this mean I got duped?!?!

but how did they survive being submerged for so long?! (I manage to read up on the Alternanthera on plant geek. It said that , "***Not a true aquarium plant. Has many color varients, and all will rot, die and pollute your tank if left in.*** ". But its still surviving... and green and stuff..

Also, can you suggest how I should care for them?

and lastly, they do still work as a botanic filter right (suck up harmful gases)?

Thanks!

 

Information on the two that can grow submersed can be found in our Plant Finder.

As for the others, they will not survive. They may do OK with their roots wet, but that's about it. Some plants that will not withstand submersion or grow submersed long term can nonetheless survive that way for a while.

 

well okay.. thanks!
