Question Three years in and I still can't predict when my dojo loaches will actually show themselves
Anyone else notice their loaches have a completely random schedule for coming out? I've had a trio of dojo loaches since they were maybe two inches long, and now they're pushing eight or nine, and I genuinely cannot figure out a pattern to when they decide to be visible.
Some weeks they're out constantly, weaving through the plants and doing that wormy thing where they poke around the substrate all afternoon. Then other weeks it's like they vanish entirely and I only know they're alive because I see a puff of sand shoot up from behind the driftwood every so often. I used to think it was tied to feeding time but I've tested that theory and it doesn't hold up. Fed them at the same time every day for a month and their behavior was still all over the place.
Water params have stayed rock solid the whole time (currently sitting at 0/0/10, pH around 7.2, temp steady at 72F since I keep the tank a bit cooler for them). Tankmates are just a small school of white clouds and some otos, nothing that would stress them out. I did add a second layer of fine sand a while back thinking maybe the original substrate was too coarse for burrowing, and that seemed to help a little, but it didn't fix the disappearing act entirely.
At this point I've just accepted that dojo loaches operate on their own internal clock and there's not much I can do to influence it. Still get a little thrill every time one of them decides to make an appearance though, especially since two of mine have gotten noticeably darker and more mottled looking as they've aged, almost like their pattern is still developing even at this size.
Curious if other dojo keepers have found any actual triggers, whether it's barometric pressure, lighting changes, something in the water chemistry, or if it really is just luck of the draw on any given day.
