they should be ok =] I remember when I had my first Dovii with my Jaguar cichlid when it was young...they were both 3" and now my Jaguar is like doubled in that size in a couple of months....and as for the dovii I sold it was to someone who wanted to have his first Dovii to be put in his 240 gallon...and yes I did check if he really did have one...man im really missing him now...I may just get another one lol =] they only cost $5 for each and plus most of the exotic fishes in my LFS sell W/C and little less C/B...
