will 2 algae blennies fight if put together?

The reason one scooter died is that they're not blennies, really: they're cousins of the mandarin, copepod eaters, and one may have starved.
I keep a starry blenny and a tailspot perfectly well together, no arguments at all. The lawnmower blenny, however, can be aggressive toward other blennies.
If your problem is algae, rather than an algae eater who will still have to be fed algae when he's eaten it all, (thus perpetuating algae in your tank) try a fuge or GFO reactor to eliminate your phosphate load and your algae will go away. If I put a rock covered in hair algae into my tank the algae would die within a week---without the 2 blennies eating it.
 
it all depends on the fish. there is no way of telling. ive seen people with midas blennies and canary blennies and nanos without problems, yet some people like me cant keep an algae blenny even with a goby..but they are really cool fish =)
 
I had a midas in with my LMB and they got along great. Sadly the midas jumped. Added a bicolor blenny and the LMB chased him into the over flow. At least my outcast perc has company now.
 
my problem is algae. but not your typical problem.

i ran every macro i could get my hands on for a while. it has haunted me for years. the valonia is the last of the problems, and is almost gone. i have no crew due to constant disruption of the rock managing my algae. there are little tufts of greenish/goldenish crap that isn't HA remaining due probably to the blenny making so much manure. (?mulching mowerblenny? heh) but it is fizzliing fast. he swines the flake food i put in about once a week but that is theonly nutrients i add to the system, and i constantly siphon dust and "mulch" heh. i've watched this system go from an overgrown jungle with so much mass, it was feeding itself, to the cheato starving out and no macros get too far before they vanish. HA was gone months ago. diatom snot gone a year ago. i can hang tough in macro id's now :D (small consolation right there)

and the thought of starving a blenny once the rapidly disappearing remnants are gone, is something i hadn't thought of. i think i would stick to one just because it is gonna get scarce and i'll have to feed it more. thanks for that perspective. :)


my tanks are so starved out and cleaned of crap from only maintenance and only 1 fish and couple gorgs for a bioload in 100+gal system. i'm home stretching it on burning out all the nutrients and hopefully most of the spores from all those different macros.
i'm hoping for march as my add corals target date. the 2 blenny idea was a momentary lapse of reason to try and speed this up for the final leg. i don't even want to do it now because of the eventual scarcity of algae that you mentioned, which IS my final goal: minimal algae without relying on the crew as a baseline. the crew will go as preventative once i'm set.

(I must admit, the system has been very stress free just watching the algae slowly decrease over these couple years, but heinously boring)
