Hi again,
So several weeks ago we had our first and thankfully, only casualty in the tank - a serpent star that only lasted about a day after a big salinity spike we had due to a broken hydrometer. It did the typical, really pathetic starfish death sequence where one by one its legs fell off, until it finally stopped moving and we felt so sorry for it that we euthanized it. It was really upsetting, but lesson learned.
Today my housemate pointed out to me that not only is one of the legs still in the tank, but it is alive and wriggling. It was some of the most bizarre sh*t I've ever seen . It was definitely the starfish leg. Any ideas? Can they just regenerate like that?
:zombie:
Also, we've been this red film on the sand for over a month now, and I'm beginning to wonder if something more serious is wrong. It looks nearly identical to all the photos of red diatoms that I've seen in tanks on the forum here, and it does diminish when I reduce the light cycle on tank and feed less. But it occurs to me that if diatoms feed off of silicate, why would they be affected by the lights? Could this be some kind of red algae instead?
Thanks!
