Comet and common goldfish are basically the same thing when we are looking at ammonia production and swimming room. Goldfish are divided into two basic types: round-bodied double tails and sleek-bodied single tails. Each type has different swimming/tank needs. The sleek-bodied single tails are shubunkin, comets, and commons. Those are the goldfish that need 75+ gal tanks.

Moving them to someone's pond is a last-ditch resort. We know you would rather keep your fish. But you have to understand a 2.5 gal tank is not a suitable home for a fish that commonly grows over a foot long in about a year. Keeping them in that tank is the primary cause of the disease.

In order to keep them in that small of a tank, you will have to do daily water changes even after they have healed and the tank is cycled. By the time they begin to outgrow that tank a lot of damage will have already been done. The sooner you can get them into a larger tank (we're talking 40-50 gal) the better. Until then: daily water changes.

I'm sorry. I don't know who told you that you could keep a goldfish in a 2.5 gal tank, but they were wrong. You can't keep a 1 foot fish in a 1 foot tank. Even keeping the water quality pristine won't help with swimming room. Not all of us are made of money either. Fishkeeping is an expensive hobby if you do it right; budgeting and planning can help, tho. I'm on a college kid budget and still have 4 healthy tanks.

TheKoiMaiden makes wonderful points!

I just want to emphasize that we're NOT trying to pick on you or accuse you of trying to hurt your fish. I can see that you care for them, and want to do the best for them. We're just trying to help you learn what is the best thing for them, so you can aim for that.

It might not hurt to ask around to friends and family to see if anyone might have a storage bin you can borrow. When I was using one, I found it in my parents' basement holding baby clothes. Its possible that someone could let you borrow one, especially if you provided them with some cardboard boxes (that can be found for free) in which the can store the former contents of the bin you're borrowing. Its an idea!

Also, a possibility might be looking into used tanks and equipment now, or when you've saved some money. Some pet/fish stores, especially independent ones, sell used equipment. Also, you could try looking in the classifieds. Often people grow tired of their fish stuff and sell it for super cheap. is awesome for this, if you're in the states.

Oh, and I just thought- there are some things you can do to help supplement the cycle. If you know anyone with an established, HEALTHY tank (no history of disease) you can take some biomedia (i.e. anything that grows beneficial bacteria on it like substrate, filter media, decor, etc) and "seed" your tank with that beneficial bacteria to help jumpstart/supplement your bacterial growth. It must come from a healthy tank, as you can't clean it in any way or expose it to chlorinated water. You just take the biomedia from their tank, keep it wet in tank water, and put it in your tank as quick as you can.

Does your tank have a light? If it doesn't, do you have a desk lamp that you could shine into it? If so, we could suggest plants that would really help with the cycle. There are a handful of plant species that are exceptional at sucking up Ammonia before it has a chance to harm the fish. So let us know if this is an option for you, what kind of light you have, and we can tell you specifically which plant to get. (Not all plants will help your situation, so we'd have to plan it out so as to not waste your money.)
Speaking of which, just today I bought a clip-on desk light from the thrift store. I'm using it for hatching baby brine shrimp to feed to my fry, but the same kinda thing would be ideal for your situation. Oh, and THAT reminds me that I've seen tanks for sale at thrift store before. Who knows if they hold water, but they can easily be re-sealed with $7 worth of silicone sealant and some elbow grease. Re-sealing a tank can seem intimidating, but really only requires some research and a can-do attitude.

I'm really pulling for your little fishies, I hope they can heal up and be healthy!

well the gravel i use is the round soft kind (doesn't remember name)as you can see in the tank but wait buy live plants and put them in the tank if so does that mean i have to replace the gravel i'm using?i think i might want this option first.yes i do use a light i turn it on for 9 hours every day the light bulb is a 15 wat one no i do not have a desk lamp unless i move the tank to a night stand but the 2.5 gal came with a filter,light,air pump and suchthe water is clear as day too so besides the bacteria gone i see nothing wrong with it i did do a daily water change god that was an adventure to get the vacuume to work.also quick question like i said i have no buckets or trash bins and can't afford anydo to being out of a job -___-,BUT would a cooler like this one here work?

obviously i'll have to cover the hole up so they don't swim in it and get stuck. if i give it a good scrubbing could it work?my mom's friend gave it to us before they moved just wandering if it would work if so what would be the best way to go about it?like the lid moving the fliter to it and such.i'll do anything to get them better also the other fish as you saw on the video keeps pecking the sicker one anyway to prevent that or even know why he's doing that to her?he'll peck her and she swims behind the filter occassional he chases her around the fake plants then they dispand then did it a few more times(i think it's becauseof the 5 second memory)

Your gravel will be fine for plants. There are many that don't even need to be rooted. Floating plants are great because they give your fish some shade and aren't fussy about gravel. Hornwort would be a great plant for your tank. I keep it with my goldfish. It does wonders to keep the water quality good, but it won't replace the need for water changes.

That cooler looks very good at a temp larger home. When you clean it make sure you don't use soap as it can kill your fish. Use baking soda or vinegar. And always make sure it is rinsed very well. Or if nothing has been spilled in it, you could just give it a good rinsing with water to get any dust out of it.

lol. Goldfish don't actually have a 5-second memory. That's just another myth. It's been proven that goldfish can remember things for around 3 months and easily recognize the face that feeds them. There is also evidence they can recognize different voices as they have surprisingly good hearing.

As to the bullying, sometimes healthy fish will bully sick fish. I've seen it firsthand with my goldfish. I had to separate them to prevent the bullying from worsening the illness. But bullying can also be caused by a cramped space, so maybe when you transfer them to the cooler it will get better. If it doesn't you will have to find a way to separate them.

It's great that they seem to be getting better! It is amazing what clean water can do in any tank. Keep us updated!

Actually bettas (Siamese fighting fish - click on the name for more info) like warm temperatures. They do best when the water is between 78F and 82F. I keep my bettas around 79F. You should start to worry when the temp goes over 82F. For the goldfish, just try changing their water with cooler water. Just be sure you don't drop or raise the temp too fast. You've been working so hard to get them healed, you don't want to stress them out any more.

Oh ya. I forgot, if you keep the tanks out of the sun and away from windows it helps keep the temperature a little more constant.
