My Jack Dempsey I've had for over a year

[CichlidScotty]

He's about 7". He had absolutaly no problems since i've had him, now he's done breathing, I last saw him laying on the bottom on his side, and i don't even know wut caused this to happen. Anyone know if it was a Disease/did he possibly get attacked. He's got scales missing all over & his stomach is bigger than ever & he's now missing many pieces under his fins.
Anyone know about this situation?

He was a main fish out of my Tropicals.

Nice jack but please tell me your tank water is not that color lol

Sucks that he died. Check your params. Looks like he has bloat.

My tank water's clear.
All my other fish are doing gd, only difference that's been done is had to add my Clown Knife to the tank, he's chewed apart a pleco when smaller, now idk if he's taken bites from my JD or if it's just cause something else.

Tank Size? Ck's get agressive when kept in close quarters. Pretty much doubles their agression.

Sorry for your loss of a good looking jack.
Did you chk the water parm? Just because the water looks clear does not mean its in good condition. Some of the pics you took the water has a light yellow color to it. May be the lighting. Just wondering why the water is yellow?

Well pix arnt usually clear with my phone, but I know the water isn't perfectly clean & I guess I'll have to perform water changes once a week, instead of every 2 weeks.
Having 11 bigger-sized common goldfish don't make it any easier.
