Bristle nose pleco with stingray

[TheReefer]

Well IMHO thats not enough filtration. As i stated on my grow out tank slighty smaller then 210g i have an large showerfilter with 70L biomedia run with a 10000L/h pump, one 120 moving bed sump with prob 40L k1 thats runned through by 2000L/h and one eheim cannister just for polishing the water and i still changed 80% twice a week.

I cant tell you what to do but i can give you my best advice as a raykeeper. Read up on rays on the forum and other places online and watch threads on diy filtration. Pondsolutions is where i find my inspiration on filterbuilds. There is some really nice threads here on the forum on both rays and filtration. IMO a 210 is way to small even for an hystrix/wallacei that are supposed to stay around 35cm wd. I recentlyg transfered my two growouts from their tank to a pond because the got to big for it and the are 18 resp 21cm wd. The growout tank is 2' wide

Wow i didn't know they were THAT dirty. I imagined then being as a dirty as 2 or 3 plecos of their size (a 1 foot stingray produces as much waste as 3 1 foot plecos), i thought that filtration would've been enough, you should make a post on stingray filtration

Since fw rays have evolved from sw rays they have an osmosis system that produces ****loads of ammonia to be able to handle the fw. So they produce heaps an d heaps more waste the other fish in the same size. Have you seen a ray turd? Even on my small pups they are big like an mussel. Imagine then a large 2' ray.

In my growout tank to be able to keep nitrate under 10ppm i had to change 80% water twice a week. Thats how much waste rays produce.

Wow, i didn't know that about them. Thanks for the info

Just curious, has the seller sent you pics of said ray or is it from your LFS???

Eitherway, is there any chance to post a pic of the ray for us to see what it looks like? coz i for one would love to find a ray that would work out for life in a 200G...

Would be like when i first found out G.Polyuranadon were true freshwater eels all over again lol...

I had no idea either until last year lol. I need one

I think someone did at one point

Freshwater rays produce 90% of their waste in the form of free ammonia, therefore one would need large tanks and sumps for dilution and a very well matured tank to cope with converting that ammonia immediately, plus great oxygenation.

All fish produce ammonia to some degree but others excrete some of the waste in non toxic forms such as urea, which need to go through a decomposition process first to become toxic ammonia, hence giving both the nitrifiers and the fishkeeper time to manage the water quality.

Ah, I see, I thought you guys were saying they pooped a lot but at the LFS I worked at they didn't poop much more than plecos and we never had an issue with plecos, I didn't know they just produced a lot of ammonia like that.

If you want rays, get yourself a 8'x4' tank and use that 210 as a sump!
