Thread: Blind Ranchu?

  1. Default Blind Ranchu?

    0 Not allowed!
    Hello guys,
    hope all is well! I have a question. I have a Ranchu which is now a bit less than an inch in size which has trouble seeing (I think). Everytime I go to feed it, it sees me coming and starts moving towards me (could it be vibrations) however, when I put the food in, it seems to swim around the food until it finds it. I have tried to look at his eyes but I can't see them at all! There's like a eye surround but I just cant make anything out. I have tried to take pictures, but don't have the skill of taking a clear shot. Can anyone advise me if I can do tests or is there some way of checking the fish physically?

    Thanking you in advance.

    There are fish born blind (cave fish) - when fish are hungry, they find food. I personally don't know of a way to check a fish for something like that.

    If it's a ranchu goldfish and looks like this you may well be stuck with a fish with terrible eyesight.

    Poor thing has been bred to look like that and its eyesight will no doubt have suffered as a result. I'm not sure how you could test the sight. Are there other tank mates?

    Hello, yes he does have another tank mate which is an Oranda. The Ranchu has not developed the bumpy face yet. Its colour is black so maybe this is why I can't see the eyes? The pupil being black in colour too.

    Perhaps, they do have small eyes anyway. If it manages to eat I wouldn't worry about it. What size tank do you have them in?

    Hello thanks all for the quick replys. Yes it eats well although, the Oranda usually beats him to the first bits of gel food. I make sure he eats just as much. I have them in a no gravel 170 litre tank. (no gravel due to bad experiences in the past) I know plenty of people say that gravel is essential, but I just don't think it is. I have plenty of surface space for beneficial bacteria to grow on (sides and back of the tank) and selected large ornaments. Thanking you again.
