I had an 10.2" inch redline snakehead in individual and jump out in the pond in almost 1 to 2 hours cause I think its being harrassed by its tank mates especially the 15.9" albino pacu I put back the snakehead in the pond and I watched over night in the pond to see if anything happens to fifth snakehead and I slept 5 hours straight and I have seen my snakehead’s gone with an cloud head damage between its skull but not floating and its not breathing and has many unseen bite marks up to its gills if I am correct and also now I am planning to sell and get rid of my fat albino pacu and my big TSN (just in case) to reduce some issues from my favorite silver aro cause starting to bite it and has couple of damage on its scales and the eye and skull seems to be fine and if I have the pacu and my larger TSN my other fish wont live long or be swallowed especially my silver aro so I have three fish left my 10" RTC and my 9.8" paroon shark and an 14.5" silver arowana Idk if it will be fine but I will try to add another juvenile redline snakehead to see if it gives another chance by its tank mates again and might have an better solution any ideas? Solution and how to reduce snakehead from jumping and dieing easily? In my opinion I think pacu is the aggressor in my pond what do you think thanks?.
