Gulpsrs should not be kept solo.mthey are a colony fish.
They fed the night before I fed one a single sprat and a few two jumbo prawn. I dont over feed them i give them small meals and they digest quicker. Done a water change before I went to bed. I was distracted as I have a newborn and ended up taking out around 70% of water. I thought dam it at the time as I normally aim for 40 - 50%. Anyway went to work and come home 16hrs after water change to all dead. They looked fine the night before. I had two survivors a peru mono and an apurensis. They're alive this morning, just hoping they stay ok.
Its £1100 ($ 1650) loss and I'm far from rich with a new baby so its all bare and i really glum about it all today.
Wow man I'm so sorry. I have Large gulpers before but unfortunately where I live my water is very high ph and hard and I had to go to great measures to bring it back to their natural environment
I wound up selling My gulpers due Me not being able to provide them with the conditions they needed. But for you to have a full on colony in an overnight wipe I would think there is a massive contamination that occured
Like you mention it is unlikely you had a water parameters spike. You might want to test the water coming straight out of your. For them to die overnight it had to be something extreme. My 8 inch gulper ate an 8 inch pearsei once and it was sideways for a week with a spine broken through its stomach wall. It lived in was fine and ready to eat. My Gulper also made it through hurricane Sandy's power outage with lackluster water conditions. These fish can truly survive through a lot so for you to had such a massive fish kill something got in your tank
I'd probably agree I'm just not sure what or how. It sucks not knowing so I can't really learn from it. Even tho I changed more water than usual I don't believe this is the cause.
Thanks for all the kind comments
