My fish feed daily every afternoon and they usually attack the feed and its gone in minutes. Yesterday I went to feed them and only a few fish would come and grab a pellet every minute or so. I noticed a green algae bloom that hadnt had all summer. I put some dye in that night, have been meaning to do that for a few days now, next morning went back to try and feed and same thing. This evening went back out and a few more fish fed but nothing like before. Algae doesnt look as bad now and I didnt notice any dead fish so not sure whats going on. I do have a heron and occational cormorant come through so I guess if a few died they could have eaten them but I think I would notice a big fish kill.

Would a slight algae bloom slow feeding for a few days>
