Hello everyone, I woke up to my first dead fish baby. Grape. My purple glofish tetra. I am pretty sure it was Grape but could have been Amethyst. So let me explain, they are both similar sizes. Grape was a little larger. I am pretty sure it was Grape. The reason why this matters is because I am trying to figure out what happened as I sit here. I tested all my levels of course, all is perfect. I have no ammonia or nitrates showing up. The PH is about 7.6. No issues with my tank. There seems to be a turf war and that is my concern. I have a larger temple in the middle of my tank, and my largest pink glofish (Princess) has been in there for the longest time and claimed it. Eventually I noticed Grape going back there in the temple as well and turfing there. there are 3 openings in the bottom of the temple. Princess ended up in one, and Grape in another. I would occasionally see them get pushy with each other. Technically Princess was there first but this has been going on for weeks already. Mostly they stayed to themselves in their own spot of the temple. I notice my glofish all seem to be turfed in plants and come out to swim in between. Grapes tail had been eaten when he was found and I don't know if that was a before or after. Partially eaten. And no one has any sign of disease or anything. I don't know what to do or if I should do anything going forward. I am so shocked at the aggressive bratty behavior I see my Glofish having over turf. I feel like I got a shark tank. How do I protect the others? Do I need to send Princess to live with my mother in a separate tank? I just am unsure what to do? To help you understand my post. Im sorry for overposting but here is my test results. I just want to show all I can to get as much of a narrowed down reason this happened in all your experienced opinions.
