I picked up 4 fish labled cutteri from a reputable shop about a week and a half ago. Upon doing some research I found there is topic of cutteri and spirulus being confused with each other. So I took to the internet and read several arguments and articals with this as the topic. After reading all the info and going off of my reputable shop, I decided to google images search both names. In my images search there came up two visually diferent fish. 1 for each name. The cutteri name brought up fish that are identical to the ones I purchased. So would it be safe to assume I got the cutteri. Sorry it almost sounds like this question answers itself, but I am still looking for other opinions. And also looking for a complete description of both fish, and there current classification status. If anyone has any info please let me know. Thank you.
