I have several questions as well as pics!

Just like the tittle says, so ill get started.

I am having purple coraline algea growing on my back wall for a while now but ive recently started to notice green splotches (see pics below) among the purple ones is it normal?

On some of my rock in one area in my tank there seems to see some rust looking stuff growing on it, can anyone tell me what it is, and if its harmful? its the orangy stuff in the pic below.

Something else that is growing on the rock but has been there for a while i just never thought anything of it, but i thought id ask its deep red and looks like a coat of smooth velvet.

i forgot the name (chalice?) of the red orange coral in the below pic but its constantly seeping spider web like stringy stuff, do i need to be worried about it getting on the other corals in the tank? anyways to stop it?

And finally is there any specific way to feed an open brain without having to wait for it to swallow the piece of shrimp i put for it, without fighting off all of the other fish in the tank? They keep robbing him of his food, and ill end up standing there for 30 minutes until it swallows the shrimp.

Just thought i throw in a few pics of the brain with his tentacles out! Can anyone give me a ID on it, i know its Australian, besides that i forgot the name.

Thanks!!

Not sure on the first pic. I'd keep my eye on it.

Second pic. The rust stuff. Looks like diatoms to me.

Looks like the chalice is having a little coral warfare with your frogspawn. I'd move one or the other and see if it keeps up.

And plastic spot feeders are sold. They're just a large circular clear tube that sits over top the entire coral. You drop the food in the top and leave the plastic in place until it's done eating.

How do i get rid of diatoms?

Coraline comes in differant colors and pink is the best.

There are many ways to reduce diatoms.
Feeding habits , and water flow ( you dont want any slow or no flow areas for waste and uneatin food will collect ).
Lighting scedule and maintance like cleaning equipment and water chages.
Also water source. Any or all or in any combination can cause diatoms.

you can also cut the top off a 2 liter pop bottle to put over coral while you feed this will keep fish away

#1. Green Coraline Algae (good)
#2. Diatoms (not good) You usually will see periods of diatom blooms as your tank matures (fist 6 months). They can be reduced by adding more water flow and reducing the nutrients in your tank (less feeding).
#3 Dark red coraline algae (good)
#4 I suspect your frogspawn in stinging your chalice, they produce the spider webs when they are unhappy. Move one of the two battling corals.
#5 I use a turkey baster to spot feed. Try a smaller food like mysis shrimp and feed after the lights are out or early in the morning before the fish wake up.
