Bit of background, In my grow out tank I have 5 Juvie Geophagus tapajos approx 6-8cm in length, along with a couple other juvenile sized fish.
Been in there for about 3 weeks now all feeding well and no issues until this morning when I find one to have suddenly died.
Checked all my water parameters and everything checked out good. Always keep the water extremely clean and perform a small 15-20 percent water change every 2-3 days. They've been eating blood worms and brine shimp and the occasional pellets.
Never kept Geos so dont quite know from experience so asking here but has anyone had something similar happen? Is there something I should look out for? Do they get aggressive towards each other or other fish when the lights are off?
Just dont want them dying on me or potentially worse I have another prized fish in that tank so dont want any aggression towards that.
Any experience or tips will be great!
