Can someone help me id'ing these two?
#1 Snail, nudi creature grazing.
#2 Red Macro algae. This one is spreading quite a bit. Is this good for my reef? How do i control the red macro or should i want to?
The red algae looks like a species of Halymenia, it will probably die off.
The so called slug I can't make out, it could be many things from chiton, to flatworm, to nudibranch, to snail, etc. Need a closer clearer picture.
HEY!! that's the plant I have in my tank!! Mine has grown nicely over the years without ever taking over the tank and every once in a while it fluoresces.
