  • Signs of vitamin deficiency in fish

    Something we don't hear about often, but is important is the need for adequate vitamins delivered to your fish via either food or added to the water column. Depletion of the body storage of any single vitamin can be responsible for specific or general disease signs.


    If your fish are experiencing fairly consistent health issues, this table of vitamin deficiencies and the signs of degrading health might help to identify a need for a different food and/or a vitamin supplement.

    Please keep in mind that some of the symptoms listed below would not present in a way to be visually diagnosed.

  • Internal Parasites and Your Puffer - What to watch for
    by edmlfc
    This is my experience with IP's (internal parasites) and puffers. 99% of all puffers are wild caught. There are very few puffers that will breed in captivity. With that being said you "must" treat any puffer you purchase for IP's.

    If you are thinking about buying a puffer make sure you have     a fully cycled tank. Ammonia and Nitrites are highly toxic to puffers. Do your research before you buy. What size tank does my
    puffer need, is the puffer I want freshwater or brackish water?...

  • Camallanus worms
    by Zulaab
    This is a first hand account of how one of our members (Zulaab) successfully killed Camallanus worms using Fenbendazole (sold as Safeguard Canine Dewormer).

    First, make sure your fish is willing to eat. If not, get it used to bloodworms (you will need bloodworms to feed the fish in the end) -- I made the mistake of first feeding NLS to the fish and it would take a while for them to eat it. They ate the bloodworms quickly and had no problem stuffing themselves with it. ...

  • Puffer Dentistry for small puffers
    by imagirlgeek
    Last night I moved all the South American Puffers from one tank to another. I took the opportunity to clip their teeth since I had them out of the tank anyway. I finally got the ratio of MS-222 to water so that the puffer goes under in about a minute. All the times prior to last night, it took about 10 minutes, so I wanted to document and share this info.
