My fish have been acting oddly lately, I have two grass carp and when they are stresses they Ďbleedí. By that I mean they look like salmon do when theyíve been migration to spawn.

Parameters are all good, oxygen levels are up as Iíve moved from a 60lph to 100lph air pump.

This pond is in full sun at this time of year for 95% of daylight hours. Iíve never had a pond that gets so much sun; Iím wondering if this may be causing a problem and is stressing them out. Iíve rigged up a bit of a sunshade this morning to give them some shade but wondering if anyone else has noticed if so much sun can cause problems for the fish?

I donít think it helps because Iíve had green water for nearly a year and the last few weeks it is now clear.
