My redtail has been a healthy fish for about two years in the last week or so his skin started turning reddish, he stopped eating, and now he's getting sores and looks like he is going to die does anyone know what this is and if there is a way to save him or not?

    Check you water levels. There is usually a way to save them. Need to find the cause. Any other signs?

    Some times adding some live fish will get them going again.

    It sounds like it may be flukes. One of the characteristics of this disease is unusual racing around the tank. See this link: Flukes disease

    I have a 14 inch and he swims up and down during feeding time....but my retail shovelnose is smaller and I do notice him doing what you describe...but what worked for me is throwing in some dry baby shrimp and he eats and calms down....but it should be okay these fish are sometimes playful

    This is exactly what my lungfish was doing before he died. Sounds like its cotton wool disease. It effects them from the inside out. But not to worry! My etc was in the same tank and he was able to recover from it with the help of medication I bought at the pet store. I used maricyn 1 and 2. Try to get the liquid form it works better than the powder. He will likely lose his appetite for a week or 2. Just give him feeder gold fish he should eat them. Make sure you take everything out of the tank and clean it really well. Best of luck to you and your fish!

I am new with the RedTail Catfish, but I did find they grow very fast.
I'm wondering if a RTC live in colder water than 68 degrees. I am considering putting it in my pond, that is well maintaned and all tests of the water are great. But it's the winter I'm worried about, any thoughts on that...

    No they don't live in cold water and winter in a pond would deffinatly kill it unless you got a good heating system for the pond.

Hi I ended up with a red tailed catfish (because someone thought it would be great for my pond). This fish is beautiful, but far too large for my pond and will surely eat my koi (who are much smaller than him). I have no idea what to do with it. He's a beautiful fish and I'd like to find it the habitat it deserves, but it isn't here. I live in South Louisiana, if you know someone who would be able to properly house him, please contact me ( Thank you so much for taking the time to read this! d

What are the dimensions of a 1,500 gallon aquarium?

  • Charlie Roche - 2012-01-03
    A 1500 gallon tank is usally made 8 feet long by 6 feet deep and 4 feet wide. However, there are no SPECIFIC dimensions as you could have one made that is perfectly square or very deep. Regardless, make sure if you purchase something this size, that it is extremely well made or professionally made. Some have broken with pressure of water when not done correctly.

we recently purchase a red-tail cat fish. He seemed fine at first, eating a lot, but lately he won't eat. Can anyone tells us why that would be? we have been feeding him what the petstore told us to feed him. It's been a few days, but now he does not seem to be interested. Please help!!!!

    he may have been over fed or may not be feeling so good, try some veal beef heart fresh at the supermarket cut small, if he does not eat that then get back to us on treatment of RTC

    I have two redtails "Ace" which is about 9 inches long and "Big Red" who is over a foot long. I feed them shrimp,talapia, worms, and very far and between I might give them a feeder. I find that they eat better being fed every couple days instead of twice a day or everyday. I also do a 50% water change every two weeks and a 75% change once a month. They are in a in door pond/ huge aquarium but clean water is key to keeping them healthy and happy. good luck

    I have an etc too. When he's being a fussy eater I throw in a few feeder goldfish. They love to chase their prey and even if they don't have an appetite they'll eat the fish because of the thrill of the hunt.

Marvin, my 4 yr. old rtcat is my best buddy. He loves to be petted, comes to the top and blows kisses, and loves to have me feed him by hand. I am experiencing a problem though. One other time he showed this quite blue cast to the area behind the eyes and down to the midsection. He is also flared out when he breathes. I do 1/4 to 1/2 tank changes every 3 weeks, and monitor his temp. daily. He is definately under stress right now. Need help and advice. I am cleaning the tank tomorrow. He eats beef heart, and has done this since I got him as a very little baby. I don't know what I would do if I lost him. he is getting older, would his appetite change?

This might seem bad, is it ok to keep my red tailed catfish in a 55 gallon for the rest of his life??

    Impossible, I have a 125 gallon and am already thinking of building an indoor pond for my 2 one just adopted last week RTC and 1 pleco.a 55 is like a cup of water to a redtail as they grow.Good Luck
  • Wei - 2011-01-17
    Yes, his very short life.

    Chances are, he will break your tank when he can't turn around in it or he will die of bad water quality. They are more powerful than they appear.
