So lets take this a step further, post why you think these odd matches in fish tolerate, accompany or protect one another. With the obvious reasons like breeding/offspring out of the picture why do they do what they do? Protection from predetors, sharing of dominant roles, cohabitation in natural habitat etc...???
Evojoey started a good thread about his geos defending his ray which got me researching nuclear-feeding association. One of the reasons I started this thread, to find different reasons and types of fish with odd husbandry and why.
