Hey guys, I ordered some amazon frogbit online and got them about a week ago. At first they seemed to be doing fine, but about 2 days ago I noticed lots of them turning brown, starting at the center of the leaf. I have my filter partitioned off using airline tubing so they don't really experience any movement. I figured this is just them adapting to my tank, but it seems weird that they didnt do this for the first 4-5 days. Also, I dose Seachem flourish + excel. So do you think its them adapting or possibly something else? Thanks.
