A sick rose
Roses can die from bad water conditions, over stressed condition such as lack of food and poor lighting.
Personally I have not lost a rose to any of the above, only to Power heads and filter intakes, but that was in my early years of owning them.
I feed them every 3 days.
Spot fed at night and what ever they can catch from the morning Mysis feeding.
I have never had a rose die from splitting either as I keep the water pristine with water changes.
I have all live rock and live sand to
help keep it as clean as possible, a huge clean up crew and plenty
of pods to keep it all cleaned up.
Loads of snails, some queen conchs, Medusa worms, Bristleworms and allot of other funny looking critters come alive at night.
Personally I think it’s the building block of a healthy tank . A large clean up crew that will eat all of the waste and excess food, thus keeping the tank sparkling clean and clear.
I have no algae at all on the glass in my large rose tank because of the clean up crew. I do however get a white film on the glass and I use the floating Mag Float on it every 2 or 3 days. I never disturb my tank, all rock and Caulerpa that I keep in the tank is left undisturbed. Caulerpa is kept in check by the yellow tang somewhat but I do thin it on occasion. It helps to keep the water clear and adds a natural appearance to the tank. (just my opinion again)
The bleached Anemone
When or if your anemone looks like this, it is very sick and needs clean water and lots and lots of food. These pictures show my first anemones that I ever bought, when I got them I thought they were beautiful, only to find out they may be beautiful, but are very sick.
When they got their first meal they bubbled up great, but it took several months of TLC to bring them back to where they should be, red and beautiful.
Here is what I use now for sick Anemones that need special care. They can stay in the tank and have water flow through it but it keeps them from hiding behind rocks where I can't help them. I also use them for Clones that need special care. You can find them at WalMart or some Walgreens in the bath dept.
As you can see, they will eat when bleached.
These are pictures of bleached Roses, severely stressed and in need of care.
And what they looked life after a month of TLC
All of these were some of my first Roses when they arrived via UPS overnight mail. They are now what is in my main rose tank.
Edit, they were sold before moving out of state but I have started back with them.
