  1. Are you a UK company and can I buy any of your fish? If you are an American company can I buy your fish but would the transportation costs be exorbitant?

  2. So are you saying that the common pleco will survive in an outdoor pond and would that also be the case in UK?
    I have been a keen keeper of pond fish and cold water, tropical and marine fish for 20 years now and have always believed the common pleco to be a tropical fish

    1. You are right Stephen. Common pleco should be brought indoor during winter if the temperature is bellow 15 degree celcius.

  3. I want to use bentonite for 500 sq ft pond with 18-degree slop, how much bentonite mix with how much soil (medium soil-loamy type)? how thick layer is required to seal the bottom? please reply soon.
