A bit of an update, been a bit on these tanks. Have dealt with a couple mystery deaths in what have been seemingly very healthy acting fish. They have showed no distress or visible signs of anything wrong and have been eating like champs up until their deaths. The deaths have occurred both time at night with me finding a dead fish in the morning.
Lost this one first a few weeks back
Then last night I lost the calico tiger
At this point Im done purchasing any more replacement fish. I will keep the existing fish until they grow old (IF THEY DO), but if I lose any more it may come down to me condensing all the goldfish into just the one tank instead of two. The orandas, especially these "Yuanbao" seem like the compact body does show up with some swimming issues but I feed them the smaller sinking pellets with one that is very specific to prevent any bloat or swim bladder issues. A very high percentage of their diet is NLS foods. Dealing with these highly line bred, man made fish that are basically ticking time bombs has made me rethink keeping them, or at least adding or replacing any more.
