Well the sag's been in the tank forever, and in the front corners since the beginning of the year. I did a complete re-aquascape a few months back -- took out
everything except the polysperma & the crypt, and rearranged it all to accommodate a 2nd piece of driftwood. Ended up giving a few plants away that I couldn't figure out where to put back in
Thanks for the warning, tho. I'll certainly keep an eye on it.
