Temp currently 30 and has been for a few weeks gettin rid of whitespot but there is no sign of whitespot anymore

All fish looked fine and healthy, convicts have laid eggs and real protective of the eggs so all other fish stay away, have two convicts two peppermint bristlenose BGKF albino shark redtail shark, and HAD two electric yellows, until i just got home from work and noticed one of theyellow labs was dead, hard as a rock mouth wide open on the bottom of the tank, had no signs of fights looked fine, does anyone have an answer??

Maybe stress? tanks to small for the fish, giving the other fish no where to get away from the convicts, marks or not i wouldnt like to be chased alot which would have happend with the convicts. Temps also fairly high as well

well the funny thing is the convicts dont chase the yellow labs? i had two gts in there but have moved them into another tank as the convicts and male gt had a HUGE fight, they were doing fine until the convict laid her eggs than got more protective. the temp was high to rid the whitespot which is now gone so i have lowered it, today it was strangely high, but it has been high for two weeks and nothing has bothered any of the fish....

Don't know anything about these type of fish so posting in the right part of the forum you might get more help.

Your tanks sounds overstocked to me.
