Amur River or grass carp. Hopefully the triploid(sterile hybrid).If they are breeders they can escape into the environment and become an invasive specie. They(the breeders) are illegal in most states.

    Yep. Amur, or white carp. They get large and eat weeds like no tomorrow. Unfortunately they breed like wild as well unless you happen to have the sterile (triploid) version. Luckily they only breed in moving water and will not breed in a lake or pond. Hence they are not really the threat they are made out to be by many.

    Here’s the view of them you are most likely to see in your pond:

    and an idea of how large they get, but I have seen them larger than this one:

    Hope that helps

    well you want to make sure his home is clean.
    Always condition the water with a dechlorinator.

    Is he bloated at all? as long as he’s eating at least 2-3 pellets a day then he’s in good shape and you have hope!

    Bettas will become very lathargic and dull if their water is too cold. on amazon.com you can easily order a 7 watt heater especially made for environments 2-5 gallons. ideally you want your bettas in water that’s 76-83 F they’re tropical fish who thrive in warm water.

    Add some freeze dried blood worms to his diet and see if that helps. there is something called “bettafix remedy” that Has been a real saving grace for me. I’ve delt with fin rot, fungus and listlessness for whatever reason and this medication is great. It’s derived mainly from a relative to the tea tree and also helps destress the fish. (btw sick fish need warmer water to heal)

    Hope that helps!

    these fish are called triploid white amur or grass carp. they are acually minnows. they come from the amur river in china. the eggs are pressurized to triploid them making them sterile to prevent over population in public rivers. these fish are vegatarians and when small they can eat 3 times their body weight a day. when they get larger their metabolism slows down and they don’t as much. they should be replaced every five years @ 10 to 20 per acre
