Hiya and welcome :hi:
I breed L260 in 24" to 32" tanks with external filter and spray bar, aquaball internal filter with flow directed across front of caves. Temperature 27 degrees. Simple set up, thin layer sand substrate, enough caves for a pair plus extra one, and a piece of bogwood
I don't do anything to stimulate them but they get 25% water changes every other day then every day once they have eggs/fry :thumbup:
