The Comet Goldfish is much like the common goldfish, but is a more reddish orange color and has a much longer, deeper forked tail fin!

I got a Comet Goldfish 3 days ago. I know it is a male. I named him Gil. He is is the only fish I have at the moment. I have a question. I have had been told that your fish can like being a pet like a cat or dog. Is that good for a fish? If yes could I try with him. He is the only fish I have at the moment. I also want to get a place for him to hide, I have silk plants, but I would like something he can go in to hide from my cat. My cat and him are cool but my cat is a bit of a hunter. So I think he likes more hiding spots. What kind of things are good for him?

    If you go to pet smart look for the SpongeBob decorations and you'll see the pineapple and tiki house those might help.

I have a thirty gallon tank in front of a kitchen window. I have seven comets ranging from an inch and a half to three inches. The last two that I bought were very small in hopes that they would grow up into bigger fish as the older ones pass. My question: Why would these two latest purchases be loosing their coloring? One was white with orange dots and the other was orange with black markings. Now the first is solid white and the black on the other is barely noticeable. I bought these fish for their markings and now the markings are gone.

    Goldfish color changes are usually due to genetics, and they will often change colors within six months, or even years. But it can also be a sign of illness, so watch them closely. Parasites can be a cause of color change.

I am a pre-k teacher who is thinking about a classroom pet. I need something easy and fun. I was reading on a teacher blog about a pre-k teacher who got a comet fish. She seems to enjoy it. I am not sure if I should try a comet or a beta. Comet seems more entertaining but beta seems easier to care for. I think I have a small tank but I have no filter system and I would have to shell out the money. Beta all I need it a bowl it sounds like. Any comments appreciated. It is a big decision. Thanks.

I have a 180 gal pond with 2 aerator/filters and live plants. There are 7 2'-3' goldfish in it that I have owned for the past couple of years. I recently bought 4 more goldfish at the store. One ended up having fin rot and is in a hospital bucket receiving medicine. 2 of the new ones are happy and perky. The other new one is extremely lethargic. It swims normally when it decides to swim, but mostly finds the places with the least current and just floats. It does eat. I managed to catch it (which was difficult) and examined its scales and fins for any obvious problems and didn't see any. All the other fish are still happy and frisky, and I haven't seen any of them picking on the lethargic fish. Any ideas about this little guy?

    Maybe you should isolate that fish as well. Consider medicating the water and just watch for a couple days to make sure it doesn't develop any signs of a contagious condition? And if he seems to be getting better, then put him back in the pond.

    They are easy to breed with the right setup, and it can be fun. Here's a quick over of Goldfish Breeding.

Hi, I'm a teacher and have had three beautiful Comets for 6 months, since my students won them at a Halloween carnival. We did a lot of research and have them set up in a large tank that we regularly clean. We'd like to upgrade the tank in terms of decoration--currently there is none--but don't know what works better, silk or plastic plants? We've read that plastic can poke fragile goldfish eyes, but silk can get frayed and eaten, thus causing intestinal blockage. Help, please? We'd really love to keep our goldfish happy and healthy for years to come. Thanks so much for any advice you can provide. ~Margarita

    Any of the choices will work!  The silk will give more movement and action in the tank.  I prefer silk or live plants.  To fray or break there would need to be something causing it besides the goldfish.  Make sure to properly clean anything you put in the tank.

    Goldfish are pretty sturdy unless you have bubble-eyes or telescope types. Plastic should be fine for them. Ive kept them with plastic and live plants and had no problems. Live plants are the best for the aquarium but they may need more maintenance like fertilizer and gravel they can grow in. Ive no experience with silk.

The next few questions might sound a bit odd but I’ll give it a shot. I activated another tank and chose to do an experiment with feeder fish. I purchased 12 Comet feeder fish and 24 Rosy Red also feeder fish hoping to become pets? My expectations might be a bit unrealistic but they have spectacular markings that are interesting and beautiful. I do realize that they may have stunt growth but is there a change of recovering as a quality fish? Should they be feed differently? And can they live as long as the so-called quality fish?

    Feeder fish can make fine pets! Treat them with the same type of care as you would for any other goldfish, including the right environment (a large aquarium with good filtration), good food,and  regular maintenance. The Rosy Reds are  tropical type fish rather than coldwater fish, so be sure to have a heater and thermometer to keep the tank warm enough for them. Also, goldfish are a dirtier fish, adding a large bioload to the tank, so frequent water changes will be needed to keep everybody healthy.

I decided today that I wanted a fish! So my dad took me out and bought 2 comet goldfish and they are small so they are in a 5 gallon tank with a filter.  Water is cold and there are plants in the tank! They were fine when i brought them home but about 2-3 hours of being in the tank 1 started lying on the bottom of the tank and stayed there for a while. The other will swim aroud then lie at the bottom. They are still breathing but barely moving... Should i be worried? They will take turns lying down and i have been telling my little brother that they are 'sleeping' am i correct in saying this?

    It's a wonderful thing that you want to keep fish. I'm glad you're father helped you get one, and the goldfish are some of the easiest fish for beginners and great pets. Not sure what the problem is, it could be that they are adjusting... or there could be a problem with their water. The first thing I'd check is the temperature and make sure it's not too cold for them. Also, if you're using tap water, a water conditioner that removes chlorines and chloramines is necessary. Also make sure the filter is providing plenty of  water movement so the water stays well oxygenated. Good luck!
