Here is a recent paper looking for the build-up effects (not specifically pheromones) in recirculated water on growth of some fish ...

This is actually a good question and I like how Mats has divided them for you by rate of growth.

Rate of growth in loricariids will be determined to some extent by the loricariid's diet preference. It is a lot easier to "power feed" a carnivore on high quality live foods than a wood eater. A ...

Congrats! Lovely specimen. Keep us updated with the hatch!
