Well, thats the end of that, cleaning out the tank.
Long story short, came home from a 3 day shift at work to dead fish. It appears that the trigger went berserk, ate the last large emerald crab and most of the angel, foundering himself in the process. I thought he had gotten the wrasse as well, but the little guy turned up a couple days later in rough shape, must've successfully hidden during the slaughter. He struggled with an infection for almost a month, thought he was going to make it at one point, but eventually kicked it. Last living pic:
I checked water after the debacle, nitrates a bit high at 20-30ppm but nothing else apparent. I believe i had just been keeping the tank too warm. The heaters were set to 79F but my water was around 86-87F at the time of the incident. Its my theory that my previous powerfeeding in conjunction with the high temperatures and my 3 day absence put the trigger into a frenzied state.
Very discouraging, things were going so well by my estimation. People had warned me about CTs going psycho like this, but i thought a 3.5-4" fish was not yet a threat. How silly of me. This is the second time ive wiped out this very tank in as many years.
Anyways, i am no longer "feelin salty". I am sans fish atm, taking some time to build a few more tanks and repair/refit my equipment. If anything, i'm "feelin fresh" moreso looking to the future, learning from mistakes, hopefully put together something lasting in the future.
Thanks for reading.
