Sunday morning I woke up do a dead juvanile Pleco. I figured it was from a cichlid ramming him or a larger pleco smacking him. So I fished him out and went about my day as normal. Later that evening was water change time so I head downstairs to get started and one of my electric blue acaras is laying on the bottom looking like its been splashed with acid on one side. So I open the tank up and theres 8 more dead juvanile plecos floating in my water. Upon closer inspection my angels look like they are melting.
Rather than waste time with my test kit I start draining the tank and do a 95% water change. As I am doing the change I remove all the dead and start moving rocks to try and find more just in case. Under A piece of slate I find 3 pieces of earthworm (i cut em into one inch sections for my fish) rotting.
I changed my substrate about 3 weeks ago and have had no problems since just doing normal weekly water changes My filter media was kept intact during the change and I kept all my lava rock in tank water with the fish to keep the BB there alive as well .
So near as I can figure My bacteria colony was a bit low from the substrate swap but could handle the work load. Until a handfull of worm decided to rot under a rock causing a spike. That spike killed a pleco (or two) as they are sensative and that caused another spike. That spike built over a 12 hour day and domino'ed till I came back to the tank.
I lost the hurt acara and I no longer have a bunch of juvanile plecs to rehome. One angel did not make it thru the night and I expect one if not both of the others to go today. ( left my wife the long handled net on the tank to get them out for me).
What I do not understand is if it was an ammonia spike then why is my other Electric blue acara in mint condition as are all 3 of my Senegal Bichirs and the remaining plecos is my tank? None of them are even showing a mark which makes me wonder if it may have been a food issue.... but the only food in that tank and not in my other was the nightcrawlers.... maybe one of em had some kind of poison in its gut or somthing...
gonna continue water changes nightly for the week to try and make sure its stable.. what a crappy crappy day.
