I know that eric bodrock talked about adding livebearers to naturally introduce natural hormones, though that may not be nessescary because they have spawned for you before. Other than that spot on.
Awesome fish do not have any experience with them myselves but know of one person in new zealand and one person in the netherlands that has spawned these. Theres also a article on planetcatfish.
This is what i do for tubifex, first squeeze all the air out of the cube then take the cube out of the water then squeeze all the water out, then it will sink is my experience
I know of cases of suppliers saying this to have an excuse to bump the price up without there being any restrictions on the species, I believe tjat case was l134
