2 seperate questions for 1 tank.
1) I put this Dwarf Water Lettuce in my tank on Saturday. Today, I noticed some die off and the leaves turning translucent. My tank is well planted, is a 16 gallon, new, and gets 3 pumps (I have crypts and some stems with root tabs as well) of Easy Green every friday on Water Change Day. Do you think it's just a matter of new tank so it has to adapt and melt a bit? More ferts? What do you think is causing it?
2) What are these squiggly black things in picture 2 on the sand? Is it fish waste? Snail waste? I have 6 baby Corys and 3 Otos with a bunch of pond and bladder snails.
Thank you in advance?
