my ray tank was 94 degrees a few years back when the heater stuck on. Rays were fine, just really hungry!
DavidW;851518; said:90 is no problem for a ew days or a few weks even , as long as there is plenty of airation. ( warmer water holds less oxygen but makes the rays more active) Sometimes it is actually useful and is part of a good quarantine program as it interferes with the life cycles of some internal parasites.
DavidW;852825; said:The water temp in the Amazon doesn't change much at night as the air temp is still hot and the sheer volume of water prevents significant heat loss. The sudden drops happen when it rains, cold rain from high up, this also increases the oxygen levels in the water and the availability of food, which are breeding triggers for many species of fish down there, especially when the seasonal 'wet season' constant deluge begins and the fish are able to migrate back into the newly re-flooded forests to search for much more food.
When I was night fishing for Discus down there I was very taken by surprise by the coldness of the rain despite the air temp of over 90F( check my site for pics. http://freshwaterstingray.com)
