Comet Goldfish Variety Pack

Skavatar

Hi, i've been lurking for a few weeks. Just got into pet fish. Started off about 6 weeks ago with two 20 gallon patio ponds and 40 .16c 1" long feeder comets from Petsmart. About half were full orange, many black, some mostly white and a few orange and white.

Last week I bought a tank on sale for inside the house. I picked out the most notable fish from the patio pond. There are six 2" long goldfish in the new tank.

I still have 4 of the black goldfish that did not turn orange. They have a metallic olive green color. Only one of them have a long tail.

This one was previously black. Now it has a light orange body with black dorsal, caudal and analfins; with a short tail. Also three surviving orange and white ones. I guess they're called Sarasa? The one in the far back has a tall body and rounded caudal fins, so I'm guessing its a common. The two closer to the foreground have long tails.

This one may have been a solid white or solid orange when I first got it. Now its a yellow or light orange color with a long tail, the tips are white/clear.

Wait.. did you say you bought 40 feeder goldfish? Please look at the goldfish care link and you may consider bringing almost all of them back to the store. You can’t unfortunately keep them alive at high densities like at the store.

I think you were following the inch per fish idea but it doesn’t work for Goldies because they produce so much ammonia. Get yourself a water test kit (really expensive I know) and learn about cycling the tank. And they can grow really fast. If you want a big community of fish take them back and ask on here for stocking suggestions.

Common or commit goldfish grow to be about 1 foot to 18 inches long and fat. They are good for a large pond, like maybe 3000 gallon capacity, and are often used as outdoor fish like Koi. So you put 40 in a 20 gallon pond? I don't even know what a 20 gallon pond is. I hate to say it, but I think you need to re-think your decision.

When giving 3k pond advice please follow with -please do not release your fish to a local pond or lake if you care about native fish and salamanders and frogs. Also there is Nothing wrong with the large backyard pond for goldfish but I am of the camp that you can keep the long-domesticated comet goldfish in a 20 gallon tank or container pond but 2 max and only if cycled (O amm, nitrite) and then you grow denitrifying bacteria (turn nitrates to n gas) so you don’t have to rely on frequent water changes- just occasional ones. I do this with porous lava rocks and/or 2.5-3 inch gravel (low o2). Then you can properly stunt them with their own adaptive hormones ( yes intentionally) which doesn’t cause health issues despite common fish myths (lore). Research actually says carp can live longer stunted in wild. With these methods my fish have lived 15- 21+yrs in aquaria with room to swim properly. None ever had health issues during their long lives. Small active healthy interactive fish.. But!! Comet Goldfish in the aquaria are not appropriate for modern popular sterile tank keeping methods. They need a healthy cycled tank (0 nitrates and ammonia) AND a hefty tank microbiome allowing for low stable or 0 nitrates (that allows you to do infrequent water changes keep parameters stable and encourage stunting). Btw stunting in gf is different than stunting in mammals from malnutrition. GF release hormones to regulate size of competitors and themselves in the process. Their internal organs do not keep growing out of proportion as is commonly stated here but organs can get affected with fatty liver swimbladder disease and kidney failure from internal fat buildup and overfeeding. So my contrary advice is to keep just a few fish for your 3 setups but measure your water parameters frequently so you can tweak your cycles as needed until you get the hang of what works to stabilize things.

Yes, I should have mentioned that I was new to fish keeping and just jumped into it with out any research or knowledge except what little i've heard about goldfish hardiness.

At the 3rd week they started dying. I did a bunch of research and learning. Then I bought a 2nd patio pond and split them up. I bought the API pond master test kit, big bottle of Prime, etc. I put pothos, hornwort, water lettuce, and hygro in them. At this time ammonia tested 0, but nitrites were high. I did 50% water changes and used 5X Prime. They were both cycled 2 weeks later. Haven't lost any more fish since.

I got this new 29 gallon aquarium 2 weeks ago on sale. I took half of the filter media from the blue pond filter and seeded the new tank filter. currently 0 ammonia, 2ppm nitrites, doing 50% water changes and dosing 5x Prime. Also put some pothos, water lettuce, and hornwort in it.

The black patio pond has a Fluval U3, I added extra biomax ceramic rings to it. The blue patio pond and new tank has a Tetra i20, replaced the factory filter bags with poly fill and Hagen/Fluval biomax ceramic rings.

Also, when they get bigger I am planning on getting this 100 gallon stock tank to replace the two 20 gallons out on the back porch. currently on sale for $70

or this 110 gallon for $75

the indoor aquarium tank is most likely not gonna be able to be upgraded. my wife was hesitant to let me get it at all.

Minimum for 2 singletails is around 200 gallons. For 40 you'd need at least 2000 gallons. Please rehome all or most of your goldfish to a suitable pond or build a large pond.

I cannot agree at all that you need 100 gallons per standard goldfish. ONE 29 cent feeder fish, huge 100 gallon tank that costs hundreds. They won't ever find homes if people try to push that.

So active 12-14" fish should be kept in 20 gallons just because it's easier? What about Oscars, arowanas or common plecos?
Anyway a single goldfish needs 180 gallons, 2 needs at least 200, after that it is 50 gallons per fish. Obviously understocking us better though.
I had goldfish in a 200 gallon pond. I felt it was cramped and we built a 1600 gallon. They are very active fish and use the space of the 1600 gallon. Personally I would never keep singletails in a 200 again. However adults can fit in a 200 gallon and, with the right dimensions, have room to swim.

I do agree with MJ - infact, you should see her pond(s), they are amazing.
A 29 cent fish still does require some basic care, but lets be real... its a 29 cent fish... Not saying that you can't put a price on life, or that it shouldn't have a good home. But why go through all the energy when you can get fish twice the cost, and house them for less - people are drawn to their price, they're cheap.

Bigger is always better, and while the 1600 is a great decision, you mentioned that you felt the 200 gallon was cramped... Lemme highlight you... Its a personal preference.

For me, as long as one can maintain water quality and try to provide swimming space (a 100 gallon long tank is better than a 200 gallon tall IMO) then the fish will do fine. Sure they will appreciate more!

Goldfish don't get 14" all the time. You'll never see one that size in a tank and even in ponds many don't get that large.

Again I fully disagree. Goldfish almost never reach these giant sizes in tanks and definitely don't need huge tanks or ponds. Just because they get larger in ponds and you believe they need huge spaces doesn't mean they actually need them. They don't .

Pushing these stocking rules I don't think is responsible because a perfectly good fish keeper who has a 20 gallon long tank would not give a sweet little fish a perfectly good home because they believe these extreme rules. Also these fish are 29 cent feeder fish. We cannot ask that people build costly and huge setups for these fish. 180 gallons is ALMOST enough for a KOI.

Goldfish cannot be compared to Arowana or Oscars. They are adaptable fish and can live a full and healthy lifespan in a medium sized tank if it is kept up. The way they grow and the temperatures they can tolerate are absolutely different from tropical species.

after about 3 weeks together, they started schooling today.

Well aren't they cutie pies? Wishing you luck with them. They are quite nice and robust looking... Nothing like the scrawny ones I see at my local Walmart. This is Shrimp my Comet over the course of 10 months. Even the scrawny ones can turn out decently with some love.

feeding time, frozen blood worms, I have the maxI jet diy water polisher running (green Sprite bottle in the back) so the worms are flying around in the tank. its cool to watch them chase/hunt the worms.

 

Galathiel

Yes, these poor feeders can get quite large and can be quite messy. Large water changes will be your friend. hehe I just wanted to post and say that I appreciate the care and attention that you obviously have given to these fish. I think we've all bought them or had them given to us at some time in the past. You are taking much better care than I did way back when.
