So my stable has always been Hikari sinking cichlid gold. My vittatus tiger, indo datnoids, black diamond stingrays, clown loaches, plecos, and arowana have always eaten these with enthusiasm. Recently bought a kg bag on amazon of massivore delite. My plecos n clown loaches love this stuff. My aro, vittatus tiger, 1 of my female BD ray wont touch it. My indo dats n other 2 BD rays eat it, but not with the same ferocity with the cichlid gold. I do enjoy that the massivores r more nutritious n r bigger than the medium cichlid gold i use. Only issue is even the indo dats n BD rays that eat massivore only will take 2-3 pellets of the stuff. So I bought another kg bag of cichlid gold that should come in next week. If the other fishes take massivore, fantastic, if not just gonna switch back to cichlid gold. I always thought monsters love massivore, always reading everyones monsters enjoying massivore
