Serpent Loach (Serpenticobitis octozona)

Acantopsis dialuzona is an odd, sand-burrowing species of loach. Although they may reach up to 8" long, these peaceful bottom dwellers rarely bother other fish, besides extremely tiny species. As they spend most of their time burrowed under the substrate, fine gravel or sand is required as coarse or sharp gravel can injure them. A very interesting oddity for many community tanks!
