Is The Fish Healthy?

[leebca]

I am splitting this post into two sections. The first is determining if the fish is healthy while it is in someone else's care. These are things to look for before you acquire the fish. The second part is how to tell if your fish is healthy--a fish you already own.

I recommend that new aquarists in the hobby start off acquiring marine fish from their local fish store (LFS). New and novice aquarists need to start with a known healthy fish. As the novice progresses into the 'accomplished' or 'advanced' aquarist levels, purchases through online sources is an option. Of course, for new and novice aquarists that don't have an LFS that provides marine fishes, they will have to rely on the online sources from the start.

SHOULD I BUY THAT FISH?

Acquiring a new fish can be a very emotional event. But the best acquisitions (from a friend, breeder, hobbyist, LFS, or stranger) are done with a clear headed, properly prepared and knowledgeable aquarist. This is one place and time to avoid spontaneity! Most who offer a fish for sale (e.g., LFSs) will hold a fish long enough for the new aquarist to find out on the Internet what people's success have been with this fish and the fish's needs for a long and healthy captive life.

The smart new and novice aquarist wants to verify anything the LFS, friend, or stranger has to say about the care, attitude, needs, and keeping the fish.

The most important thing when acquiring a new fish is: Don't rush! Take time to study the fish. These are things to look for and find out about the fish:

1) Is the fish a herbivore, carnivore, or omnivore (or detritivore)?
2) Will you/your system be able to feed the fish?
3) What space is needed by the fish?
4) Can your marine system support this fish?
5) Will the fish get along with other system inhabitants?

After the above has been settled and you're sure that kind of fish will be a good addition to your marine system, then comes how the particular fish is behaving and what it looks like:

6) How scared is the fish? Most are wild caught, however the fish should not look 'terrified' or 'panicky.' Will it swim in the open? or is it 'stuck' in the corner?
7) Is the fish aware of its surroundings? A fish in a catatonic state should not be acquired.
8) Any signs the fish is 'bothered?' Is it scratching/flashing? Is it coughing? Is it 'wagging' its head? Suddenly dashing about? Swimming abnormally? Only swims at the top or corner? Don't acquire such fish.
9) Is the fish breathing normally? Don't buy a fish that is 'swallowing' more than 100 times a minute (assuming it isn't terrified or panicky).
10) Check all fins and body for scares, injuries, tares or missing pieces. You don't want a fish that has been badly handled, beaten up along the way by other fish or humans, or otherwise may be in a poor condition.
11) Are there any signs of disease on the body, fins, or mouth of the fish? Any signs of 'growths,' spots, or off-colored patches? Is its mucous coating smooth and uniform and intact?
12) Is the anal region inflamed or discolored? Don't buy a fish with obvious signs of intestinal parasites.
13) Is the fish the color and has the markings it's supposed to have? Don't acquire a fish that looks 'off.'
14) Look closely at each eye. Any fish with signs of cloudy-eye should be left with its current owner to 'fix.'
15) Is the fish eating? Ask to see it eat--don't assume the owner/LFS knows the answer or is being truthful.
16) If the fish is eating, what is it eating? Will you be willing and able to supply that food? How is the food being presented? Will you be willing and able to present the food in that manner?
17) Ask if the owner/LFS water contains any medications (e.g., copper). If it does, keep in mind the fish may be sick and under some treatment.
18) Prefer to buy a fish that has been in the owner's/LFS system for over 2 weeks.
19) Look around at other fish that are in the same system as this fish. If they have parasites or exhibit problems outlined above, your fish will likely have those problems too.
20) If you think the fish is worthy of going home with you, gather information about the owner's/LFS system. You want to know:
------ Temperature
------ Specific Gravity
------ pH
21) Finally, have the fish caught and bagged. IF DURING THIS PROCESS the fish is harmed, injured, dropped on the floor, snagged in the net, then REFUSE TO TAKE/BUY THE FISH. Pass it up. Don't be afraid to do this. Until you've paid or made a trade for the fish, it isn't yours.

If you'd done your job, buying a fish from an LFS should take about 90 minutes after you're sure of 1) thru 5).

Print out the above list and take it with you! - REMEMBER: You are not a licensed veterinarian nor a fish hospital! Buy only healthy fish; do not buy fish that need extra care or cures.

IS MY FISH HEALTHY?

So, you have the fish in your quarantine and need to check it out before it gets into to your display tank. That's very smart of you. Follow these quarantine guidelines: A Fish Quarantine Process

You want to look for most of the things on the above numbered list, plus the following:

a) Fecal matter. You should perform a de-worming anyway, but monitor the fecal matter on color and texture. See: Strange Excrement from Fish -or- How to be a Super Pooper Snooper
b) Eating habits. Types of foods and does the fish eat with gusto. Will the fish eat the right foods? See: Feeding Marine Fish and Fish Nutrition
c) Acclimation. Has the fish settled down and recognizes you as a friend? If not, you need to spend more time with the fish.
d) Monitor QT water quality closely and with proper gas content, the fish should now be breathing at a rate below 100 times per minute. If not, something is wrong.
e) Go through the numbered list above daily with emphasis upon numbers: 8, 9, 11, 12, 13 and 14.
f) Any indications of acclimation problems (strange behavior, going catatonic, unaware of its surroundings, etc.) should be noted and monitored closely.

If you now own the fish and think there is a health issue, post your questions in the Marine Fish: Care, Health and Disease Treatment forum! http://www.reefland.com/forum/marine...ase-treatment/

Good luck!

My expertise is ornamental marine fishes. Don't know much about koi. You might want to search the Internet for koi sites.
