do java ferns not root into the substrate or is it just slower? i have my java ferns planted in the substrate with just the leaves/rhizomes out, and they seem to do fine, although i notice that when i take them out, they have small roots. i wasn't sure if that was because of being planted though.
shrimp should be fine in that tank, however, it might be difficult to keep them alive since they are pretty picky on water parameters. i think it will be ok as long as you only keep a few and keep the water clean
