I put one of the tilapia in a new outdoor aquaponics system yesterday, and unfortunately I was dumb on two fronts: the system was extremely full of water (within 2-3" of the lip) and uncovered. I found the fish dead and semi-dry on the ground about 12 hours later. I tried to revive it for about 20 minutes, but it was too far gone and never responded.
species: blue tilapia
weight: 32 grams (1 1/8 oz)
length: 4.5"
age: probably 9 or 10 weeks (had it for 7.5 weeks)
