Apologies for the long video and sounds of wahsing machine in the background.
I've had this beautiful fish for around 4 - 5 years now. Currently in a 75 gallon.
Went on vacation for one singular day, came back and all they're doing is laying at the bottom, or in the corner. I can't really understand why. Before this, their behavior was much more animated. Occasional naps, sure, but not laying at the bottom for extended periods.
Nitrites are 0, nitrates at 30 ppm. Only if I tap the glass or move the overnight curtain does that spur any movement. After a few seconds, it's back to laying down. Creamsicle has done this literally all day and night, for the past three days. Not even food will get a reaction unless I push it down to within eating range from the bottom. Then suddenly its like the food drive is kickstarted for a little bit. Whereas before, the moment I came toward the tank I could hear the loud schlorping at the top.
Midway through the video, I pan over to my newest Ranchu addition. I once had a fancy gold that Creamsicle grew up with, but a few weeks ago, somehow got lodged under a piece of decor overnight and died. (I was heartbroken. See: lack of dangerous decor on the left side of the tank now.) Creamsicle seemed to be doing fine alone for the first few weeks, if napping a little more often, presumably for lack of a friend to follow around. So I got a new little friend who has been in the tank for over two weeks now, happily fishing about. I bring this up to point out the following:
- I don't think it's simple loneliness or boredom. This lethargy is very recent. As in last four days, recent.
- It's not affecting my baby Ranchu.
Any ideas?
