What species are you planning to keep with them, a volitan is going to grow really fast. The smallest you are looking to get is likely going to be around 2.5/3", they could easily double that in a year. Feeding, as with all lions can be a challenge, while a volitan will take to dead food easily, a really small one may need to start with live ghosties; as usually with most lions anyway. Transport with all lions seem to be a challenge, your source will have alot to do with it. One mistake many make with a really small volitan is under feeding; once established you'll want to feed their full every other day for the 1st year, until you see a nice bulge in the belly. Many times they will outgrow smaller species that many plan to keep them with, and become a threat. Broad bodied, semi aggressive at the least are they best tank mates. Over time the volitan may not want to put the work into hunting down their tank mates, but can still be a threat if the opportunity presents itself.
