I have a pond with goldfish and koi. One of my fish can't get up righted. It has plenty of energy but hangs upside down. 2 weeks now. Can I do anything to correct this?

My dad has a 'white' fantail like goldfish in his outdoor pond. The fish seems to be bloated at its back end, its top fin lays flat and most worryingly, it's head is pointing down, and its back lays just under the surface (sort of arched). I have thought it was dead a few times and gone to take it out of the pond, but as soon as I touch it, it swims off quickly to do the same somewhere else within the pond. Any ideas? I don't want it to be suffering.....

I have a 17 year old piranha and has recently started to lay on the bottom of the tank on his/her side most of the time. When he/she swims, its head is up and tail is down and and swims in circles. He/she is in a 60 gallon tank and he/she stays mostly at one end. We have fed him/her minnows for all these years from a supplier. He/she seems not to be eating. This has never happened before. Any ideas what the problem could be?

My Skunbunkin has been sick for a week and a half. I've been treating my whole tank (3 goldfish & 1 sucker fish) with the Lifeguardy all-in-one treatment for a 5 day treatment. Skooby started feeling better, but his belly is still swollen more on one side than the other. Also now he is staying at the top of the aquarium either for imbalance or oxygen.

I changed my water 25% day before yesterday and started back on all-in-one treatment again. What to do if Skooby is constipated (clear string hanging from butt) or he has swimmer bladder? Appreciate your recommendations to get his belly down from swelling. Thank you.

Hey everyone, my pot-bellied molly and cat farowella have recently died both in the last four days. They start by showing white/dull spots in their scales. Then within 12 hrs they have problems swimming and keeping their equilibrium, and hardly moved even when being touched, then eventually die. I keep my freshwater tank at around 76 degrees. I don't believe it's ich because of how quickly it hits and kills my fish. The only other disease I thought it could be would be neon tetra disease, but it's hard to tell for a beginner fish-keeper. Any help would be greatly appreciated.

    This could indicate any number of diseases. Spots could indicate ich, flukes, Lymphocystis, Glugea, Henneguya, etc. Bulging eyes could indicate pop eye. Holes in fins could indicate fin rot, red pest, or injuries to the fish. Try reading up on fish diseases here: Fish Diseases

Used to be very aggressive when someone new would walk in the door...but lately the past two weeks I've noticed like a slimy feel on her and her eyes look like there is a grey film over them and she no longer wants or even eats ...I've tried doing the changes to the tank as the pet store advice (changing Half of the tanks water every week) but still no luck... I have even noticed her color is no longer the same ...Please any help is very much appreciated...Side note I don't know for a fact i'ts a she but she used to be so aggressive I called her Piranha..

Hello I just Purchased my Calico Shubunkin and a Few other Gold Fish plus a Algae eater. I noticed my shubunkin might have had a parasite instead of shrugging it off thinking its a piece of poop like I did with my last Shubunkin I went and Purchased Jungle Anti Parasite Food. All the fish are doing well, but today I was watching Pumpkin (shubunkin) I noticed he is starting to get white like is it normal for when their Growing (he is a young one) for their colors to fade and change?

He is Very Active no labor breathing or anything but I have been searching sites trying to find information of them growing, and well lots are miss construed information. I may not be a fish expert but I owned two gold fish when I was younger and they changed from orange to white and ended up being a Different spices of gold fish and lived for 16 yrs. Could he be one of those too? His tail is different he has a normal top tail and a Really long bottom like a Lyre tail almost.

Please E-mail I hope to hear your feedback on this soon =)

    Goldfish can change colors depending on what you feed them. In particular, feeding more "color" foods can brighten up their red and orange colors, and vice versa. Foods with lots of carotene (spirulina, shrimp, etc.) will help brighten their colors.

    I cannot tell you for sure why your goldfish is changing colors or if it is a different species, but you may try different foods to see if it makes a difference.
