Hi...I did this page in my 24G startup thread...hope this helps:
Dangers of Owning a Nano Reef (or Why the @#$#%^ is My Finger Swelling)
We've all gone down to the beach or ocean at one point in our lives and either stepped on something, brushed against something or went running out of the water after seeing something skitter by our foot in the water. Well, know we've brought a piece of the ocean home. When we put our limbs in the tank, we are now in THEIR environment. What are some of the hidden dangers now lurking behind the glass in our living rooms?
Stings/Nematocysts
Many invertebrates have developed methods of defending themselves from attack or encroachment or even to get food by ejecting nematocysts, small capsules that can inflict a nasty sting. These animals are in a class called Cnidarians...jellyfish, anemones, etc. Reactions can include stings, rashes or the extreme of anaphylaxix.
Envenomation/Bites
Certain fish contain poison in their bites or in specially designed spikes in their dorsal fines. The most classic example is the lionfish. There is also a poison fang blenny. Again, reactions can vary from a mild sting to anaphylactic shock.
Ingestion of Toxins
Many soft corals secrete a slime layer, which, if not washed off the hands and ingested of if enters a cut, can cause extreme illness. Zoanthids are one in particular. If handling them or 'fragging' them (breaking it into smaller pieces), make sure to wear gloves and wash your hands afterward.
Lacerations
Razor sharp dorsal fins near the caudal fin can cause nasty cuts. Surgeonfish and some tangs are good examples. Mantis shrimp can split your fingertip if not handled carefully. Their chelae can smash thru shells and in some cases, aquarium walls. Some people have had bones broken.
Splinters/Bristles
Not too difficult to figure out. Bristle worms, if grasped or if LR is handled indiscriminatly, can have their small bristles break off in finger tips and cause extreme pain. Handle with care.
The most important thing to remember is that any injury occurring in a marine environment can lead to infection...and the bacteria can be quite different from the regular bacteria we are used to in our normal lives. These wounds can also take MUCH longer to heal. Use some smarts when sticking the hand in the aquarium:
1) Use gloves if possible if you have livestock that requires it or you are going to handle LR
2) Avoid sticking digits into blind areas
3) Don't buy livestock that you have no experience with if they are dangerous or poisonous and certainly don't stock them if you have small children in the house
4) Wash your hands after handling marine animals and invertebrates
5)Avoid doing tank maintenance if you have open wounds on your arms or hands
6) Siphon carefully if your tank contains potentially toxic livestock....start the siphon with a pump or by filling the tubing first
6) If you see any signs of infection...swelling, redness, pain, heat, chills, fever, etc..don't wait...get to the ER right away. Here are links to 2 threads that will help persuade you from 'toughing it out'.
