I have a 29 gal saltwater tank. I
HAD 2 yellow tailed damsels, 2 percula clowns and an long tentacle anemone. My son is in high school and his biology teacher gets saltwater animals for them to observe. That is where I got the anemone. Well, my son called me from school one day and said his teacher wanted to know if I wanted a starfish and sea urchin for my tank. I said sure they're free. I work 2nd shift so when my son got home from school he called and asked if he could put them in the tank, I said go ahead. Well, the next morning when I checked the tank there were 4 starfish and 3 sea urchins, and 2 dead damsels. The clowns were swimming at an angle also. when I got home from work all life forms new and old were dead...... except the anemone! I had to clean out the tank and do a full water change. Now, a week later I have introduced in 2 snails and a tomato clown. Starting from scratch!!!!!!!
