If your looking for the dovii extremely interactive mentality your going to be disappointed. They look like a little dovii & that's about it. So if your purely going for the dovii look and want something different from other people it fits the bill.
They're cool in their own right. They are some nasty little suckers and very skilled at fighting from the ones I've seen (attacks eyes, gills, sensitive areas and have good defense). Some can be skittish, but I've also seen others bang the tank. Growth rate is killer though only .25" a month at best so you have to be patient or buy one already 6" long. I looked at getting some, but decided the juice wasn't worth the squeeze with the growth rate.
