DMD - love the big puffies! Looks like that one might be a girl if I'm correctly seeing her vent tipping out.
If I owned my own place I'd have to have at least a few in a nice big tank. Ever thought of throwing in a head of lettuce and seeing how long it takes them to demolish it? XD
Regarding my 6 gal, water changes every other day and dumping in Prime and Quick Start worked again, as nitrites and 'trates tested all the way down to zero this morning. Water sprite needs removal again, and I put in half a dose of Easy Green.
Been able to observe the Minions (blue rasboras) more since Ryan (kubotai)is gone, and noticed that the one I thought was a decolored sub-male that was tasked with watching the late kuhli is actually a female who has no mate and still is on the edge of the group or alone. The other four are mated pairs that stick together, with both males fully colored up. Sai (betta), who'd been on an absolute nest building tear since I installed the Sicce filter last month, hasn't built a one since she died, either. And he's been angry-chasing Parona (garra), which is unusual for him, when he's not sitting listlessly in the water sprite. Considering that he and the blues watched the kuhli die, I'm pretty sure at this point at least some fish have SOME concept of death, even if its just 'predator not gonna eat me anymore'.
Ironically I went to my LFS yesterday to get some supplies and they had kubotais again for the first time in a long while. No, I didn't buy one (tho I'm tempted to see if the lone blue and a single kubotai would buddy up, I'd rather see if I can somehow get another blue male, which is unlikely given stores usually won't sell such small fish based on sex).
