Black Kuhli Loaches
I wanted a group of kuhli loaches for my sandy-bottomed 29g aquarium. My LFS carries regular banded kuhlis, but they're sold incredibly small (maybe an inch long and as thick as a pencil lead) so I'm afraid they'll get eaten by my other fish (especially the kribensis). They also for for about $4 a piece. However, the store recently got in some black kuhli loaches that full grown or very close to it and are selling them for only $1.50 a piece! Not only are they cheaper, but also the store owner says they have trouble keeping the banded kuhlis alive.
The research I've done seems to indicate that black kuhlis are hardier than their banded cousins. So...I have a few questions. How long-lived are kuhlis? I know many other loaches have long lifespans, but I'm always averse to buying adult fish because they could be in their old age already. Would a group of 5 or so black kuhlis do well in a sandy bottomed 29g? There are plenty of caves made from red shale for them to hide in, and I have some pretty low-level lighting in the tank. Tankmates will be 2 golden wonder killifish (already in the tank), a breeding pair of kribensis, a trio (1 male 2 female) swordtails, and eventually a single (or maybe pair? I haven't decided) badis badis.
