Zzsharks Posted October 15, 2022 Share Posted October 15, 2022 Hi- I am going to try some coldwater fish this year.Do you think I could have a fulval flex 15 gallon tank with 1 perlscale goldfish. I could add a spong filter or a hang on the back filter as well. I would have an air stone as well Link to comment Share on other sites More sharing options...

I would have an air stone as well I’m told the absolute minimum is a 20 gal, but a 15 should be fine as long as you can upsize it when it starts growing.

Zzsharks Posted October 15, 2022 Author Share Posted October 15, 2022 ok Do you think I would need a hang on the back filter as well on the fuval flex 15 Link to comment Share on other sites More sharing options...
PineSong Posted October 16, 2022 Share Posted October 16, 2022 (edited) I would absolutely have a hang on back filter for a goldfish in a 15 gallon. Sponge filters work great for bacterial filtration but HOBs are better for actually removing crud from the tank, in my experience. I would use filter floss in the HOB as goldfish are so messy. And he or she will need a larger tank before long. Goldies need room to swim. Edited October 16, 2022 by PineSong Link to comment Share on other sites More sharing options...
Zzsharks Posted October 16, 2022 Author Share Posted October 16, 2022 ok It would be the internal filter from in the fuval flex AND a hang on the back Link to comment Share on other sites More sharing options...
PineSong Posted October 16, 2022 Share Posted October 16, 2022 Yes, what I like about having more than one kind of filter with goldfish is that the sponge filter can hold a lot of bacteria that helps with the nitrogen cycle, and the hang on back can be filled with floss that is good at holding onto all of the muck that will be in the water.It’s easy to replace half the floss every week or 10 days or however often it accumulates to a point where it is full of poop. I usually replaced half the floss at a time, so I wasn’t eliminating too much beneficial bacteria at once. Link to comment Share on other sites More sharing options...

Colu Posted October 16, 2022 Share Posted October 16, 2022 (edited) Pearl scales can get to 8in it can work in the in the short term I would look to upgrade to at least a 29 or bigger goldfish are very messy fish and produce a lot of waste I use fluval 307 external canister filter and a ziss 300f bubble filter for my 12 in comet goldfish hob and sponge filter would be a good combination Edited October 16, 2022 by Colu Link to comment Share on other sites More sharing options...

Zzsharks Posted October 16, 2022 Author Share Posted October 16, 2022 30 minuets ago I went to my LFS and I got 20 large discus for the 2,000 gallon but my phone is broken so I can't take photos yet. I think I could get 5 more discus or some stingrays. Link to comment Share on other sites More sharing options...
