I need help guys

The tang died about 1 month back.

He was very small. But he was fine as it seemed, and I went and had a shower and came out and saw him in the clutches of the sally light foot. So i spooked the crab off, got him free and put him into me other tank. He was pretty banged up, and I feel the shock finished him off. He may have been a little sluggish, but seemed ok.

The fish were from different stores.

I noticed earlier today that my angel wasn't out, and I looked around, and found the crab with him, the eyes had been completely eaten out.

I also lost a chromis a while back. I had had him in the tank for a long time. Found him on the bottom as well, looked as thought eh crab had had a dip at him.

I've also noticed a lot of hair grass has sprung up on the LR lately.

Thank for your help.

You should also check your phosphate level as this maybe very high due to your growth hair algae, anything over 3 or upto 5 can be very bad for fish, if i have remembered this correctly.
