I have a group of 14 L. hecqui in a 55G I've been trying to get to spawn for a couple months, but so far no dice.
The parameters of the tank they're in are a temp of 78° and a ph of 8.4. (Can't remember the rest off the top of my head). No Am./Nitrite/very low Nitrate.
Current diet consists of veggie flakes, Northfin cichlid and veggie formula, and the occasional treat of bug bites.
I've tried big water changes, as well as doing a water change that's a few degrees colder. Alternating light/heavy feeding schedule hasn't seemed to help either.
I've been trying with PVC pipes (they aren't WC, so I didn't think this would be too much of an issue). Should I try regular shells? Ay recommendations on where to source shells that are large enough?
What am I overlooking? Anyone with firsthand experience keeping this species able to lend their two cents?
