My fish died suddenly. Is my snail sick or dead? What should I do?

Thanks for reaching out. Testing water quality for pH, ammonia, nitrite and nitrate is the first step, correct any problems. There are few diseases transmitted between fish and invertebrates. If problems persist, a visit to a veterinarian is recommended. Good luck.

Why is my new vanilla lobster sick, stumbling, and on its side?

Check the water chemistry. Invertebrates can be more sensitive to ammonia levels than other fish. It is always recommended to quarantine new additions in a separate tank to rule out or treat infection or parasites prior to adding to the main tank. Make sure he isn't being harrassed by other fish. As he matures, he will grow and become a potential threat to bottom dwelling tankmates.

Where can I find expert help for my fish tank filtration questions?

You should contact by email the administrators of the website (you can find general email on the contact section) and they put you in touch with the Head Vet in charge of hiring new experts. Best of luck and hope to see you joining the team soon. Dr. Orioles

What are easy, small pets for beginners? Is a cowfish a good choice?

The Cowfish, or Longhorned Boxfish, is a marine species that should be kept only by experienced aquarists. When stressed, they can release toxins into the water which may harm tank mates. Pacman frogs, leopard geckos, corn snakes or bearded dragons are all easy to keep.

Is a 1-foot marine tank big enough for fish? What can I put in it?

It is very difficult to get a good biotope in a just 1 foot long tank unless it is a few feet high. You will not be able to keep fish in it, only invertebrates, maybe a few shrimp or sea anemones. It is much harder to keep the water healthy in a small tank,and the appliances needed for running a salt water aquarium cost pretty much the same (if available) as appliances for a larger tank. I suggest you join a club of salt water aquarists who will be able to start you off perfectly. Your local fish/pet shop should be able to point you to a club.
