Do I need a bigger tank

[Tina Hammonds]

I have some feeders I decided to keep every time a few of them were left after a week or two in my turtletubs these were the survivors and they grow strong and big wondering how many I should actually have in a single aquarium or how big a aquarium should I just get for all of them I was thinking a 75? Or should it be bigger tank is kind of murky after 75% water change had to house 2 2inch turtles in there for 2 weeks got kind of dirty

Do I need a bigger tank?

That's a stupid question. The answer is ALWAYS yes.

wondering how many I should actually have in a single aquarium or how big a aquarium should I just get for all of them I was thinking a 75?

And definitely yes in your case.
Looks like there are 14 unless I'm missing some? The general rule of thumb is 10 gallons each for fancy goldfish, 20 each for comets. So you're looking at something like a 150 gallon minimum, ideally 280. But since I'm guessing you're unlikely to go that big, try and get something around 150.

Best bet is a pond here imo. Comet goldfish grow to around a foot each under proper care. They eat/poop a lot,and are very active. I have 6 in my 350 gallon pond. Cheapest way to go here is either rehome most or set up a stock tank. Also feeder fish are not a good staple food for turtles or anything for that matter, not enough nutrition and some sickness risk. There are plenty of good pellet foods on the market these days that would be a way better option to keep your turtles happy and healthy.

I would agree, nice of you to keep the feeders, but they will require quite a large aquarium in the 200+ range with heavy filtration, to keep that many of them permanently, IMO. Super messy fish that can get past a foot long easy and are heavy-bodied fish. Stock pond would be smart move, or re-home a bunch of them and keep half that many in a 100+

I would wait and see. 12 Goldiies of any kind much for 75 according to the regular rules, and comets are the biggest goldfish, BUT they may not grow very much. Feeder quality goldfish have a tendency to stop growing at a random size. Also, aquaponics people keep 2 comets to the gallon (not reccomending this - you can't match their filtration and the rules are different on a larger scale). A 125 may be enough for life, or you may need 1000+ gallons. It really depends on your comfort level and how big they get before they stop. Final size for a feeder goldfish could be anywhere between three inches and two feet, plus the tail fin. I would grow them out, keep 3-5 smaller ones in the 75 and give the rest to someone with a pond.

yes goldies especially comets can get huge I kept 2 ina 100 gallon tank that got to around a foot They are pretty cool as you don't need a heater and they are veryactive and never hide always sifting the gravel bed

Yeah there were feeders I breed res morphs and decided to let them live after they survived so long from 5 different occassions were about a inch when I put them in I have couple 300 gallon stock tanks I'll set up

Nah that's when there hatching I always feed shrimp pellets and blood worms and albinos have a harder time catching them if there Transparent looking i have better experience feeding small feeder goldfish 2 times a week till there bout 2 inches then I'll switch to perch or brim I catch from my own pond but the gold fish I got to like them I'll put them in a 300 gallon stock tank I got this
