Recently purchased a small black sea urchin, (has bright electric blue spots on its head!), settled it great for first two weeks, added to tank after 25% water change, readings are - sg 1024, ph 8.2, amm 0, nitrite 0, nitrate 20. In tank already, 2 yellow tail damsels, 1 moroon clown, 1 fire, 2 cleaner, 2 (small & med) red leg hermit. (one has shed twice in a month?) 3 extra shells in tank. All a fine, 1 damsel a bit of a bully to others, but clown is a bit of a cooler as he's at least 60 x 30mm. Noticed 1 shrimp on urchin alot recently, looking as he was cleaning him??? , the urchin was very active all around tank, then stayed near heater in last couple of days, temp is 25 - 26c. Since then not active and been loosing spikes. What should i do?
