How many stingrays?

  • We are currently upgrading MFK. thanks! -neo
the bioload determines how many fish you can fit in a tank, not how much of the bottom is covered, stingrays need heavy filtration and a huge amount of water changes, youd probably max the bioload before the bottom is covered, with stingrays you dont want it overcrowded, they require alot of room to maneuver and move around each other, and theyre not cheap so i dont even know why youd consider stuffing them into a tank like sardines in a can

I know. But, how many? is it like, 1 per 1 sq foot? I don't want to stuff them. I'm setting up a breeding tank for them but the more space the more rare species. I am aware the cost and the size and bioload and what not as I have kept stingrays in the past.

There is no formula, you need to test your water, for stingrays you would 'ideally' need to keep it as close to 0ppm for nitrates, nitrites, ammonia, and once you start getting readings you are probably in trouble, because that instantaneous reading doesnt account for the long term, as they grow into adults, that would increase the bioload, and your bio filtration/ water changes will become less effective as the rays grow to full size, i havent kept up with ray keeping for quite a few years, im not familiar with the current strategies for managing bioloads with rays
