  2. Hi Dr. My tetra has fin rot. I’ve been using API Pimafix, but it hasn’t seemed to do much good. I want to switch him to API Melafix, but I was wondering if I need to do a 100% water change first in case of overdosing or mixing of treatments. Any advice? Thank you!

  4. Are peas bad for bettas. I can only find sources from hobbyists saying they are good. But some have started insisting that it is dangerous to give a betta peas. Is this true?

    1. Bettas are carnivorous and peas do not seem to fit their dietary profile. I wonder if the feeding of peas has come about as an extension of the commonly talked about prophylaxis for buoyancy disorders in goldfish? Even in goldfish, I’m not entirely certain that it works to prevent buoyancy disorders.

  5. My company has an A1C test for cats, dogs, monkeys, birds and horses. I wonder how fish would test via A1C. Is fish food elevating their A1C? or common diseases? Ray

  12. Hello. I have a dojo loach who has a wound that got infected. There are many infection treatments available for fish but little information about which are safe for scaleless fish. Do you know if these are safe for this type of fish? – amoxicillin, penicillin, cephalexin. Any other broad spectrum antibiotic you would recommend over these? I have tried the usual ones found in the fish stores and now have ordered nitrofurazone over the internet so will try this when it arrives (assuming the fish is still alive by then).
    Thank you for your helpful videos and advice. Really appreciate the effort and good inforation.

    1. Antibiotics are very targeted towards fighting bacteria, and almost all are safe for scaleless fish. The only class of antibiotics I would avoid using in scaleless fish are tetracyclines. Not because I know it to be unsafe for them, but because tetracyclines are considered irritant to urodeles.

  13. Hello Dr,

    I have 2 baby koi that are breathing through one gill, and one of them keeps flashing violently. I’ve tried tea tree oil and it seems to help temporarily. I’ve made the assumptions they are affected with gill flukes but can’t confirm as I don’t have the equipment to inspect. What treatment would you recommend?

    Thank you,
    -Tariq
