I am new to saltwater. I have a Coralife 32 Biocube that has been up and running for 2 months. Got my first fish (Royal Gramma) a little over 2 weeks ago along with some hermit crabs and astrea snails. Water was looking and testing great. Inhabitants looked healthy and happy. Then 4 days ago I added another fish (yellow goby), a skunk shrimp and some Nassarius snails. The Royal immediately began terrorizing all of them. The goby went into a hole and only peaks his head out once in a while. The Royal sticks his head in the hole with his mouth open wide on a regular basis. The shrimp was cornered in the back where the Royal just hovered over him. He is even nipping at the new snails. I decided to try and give the royal a "time out" and my husband and I tried for 2 hours last night to catch him (we couldn't). My Biocube looks destroyed now. Rocks knocked over, water all cloudy (still after 12 hours) and this morning the royal is nowhere in sight. Did not come out when I fed which is very abnormal. He is a very eager feeder. The shrimp however is very freely roaming about. I am literally sick to my stomach right now. I had to go to work and won't be back home for another 9 hours. I got the biocube to have a relaxing hobby and now I'm just devastated and feeling sick to my stomach If anyone has any words of encouragement I would love to hear them.
