bleaching is the same as dying.
they can lose coloration and bleach while still retaining polyp tissue from
1. Temp swings (do you have a temp controller on the tank?)
2. suddenly too much light.
3. too little light.
what happens when they “bleach” is the zooxanthelle dies, while the coral remains alive. However the coral cannot live long without its zoo so then RTN sets in.
that’s a really basic and ****** explanation but so you understand what bleaching is.
