Flagtailscan be very aggressive the tiger may have been the aggressor when the lights where out and keeping at bay during the day
Definitely not debating that flagtails can pick on others. But in this case I only ever saw the dat be the aggressor. The dat never bothered the flagtail until I took the pike cichlid and severum out. Once it was just the two of them left around the same size, the flagtail would simply swim by the dat's line of view and would be chased down for it. Not sure if it's the silver dollars, the Oscar, or the combination of the two, but all's well now. From time to time the Oscar will flare its gills at the dat. But other than that there is little to no aggression for now.
I've grown the dat out from 1 1/2". So most likely I'll have him to grow out awhile longer
I feed him about 15-20 massivore pellets a day, 6 days a week. I agree the 120 should be ok for awhile longer. But man it sucks having a bigger tank and not having it set up lol! But, all in due time. Having a friend that I trust to babysit my pleco if needed is nice peace of mind. Current filtration is 2 AC110 and a marineland C-360. The canister is nothing but bio media. I have been tossing around the idea of pulling out my pleco's driftwood cave, but my pleco keeping instincts keep telling me he needs his cave. And the dat seems to like taking refuge behind the driftwood as well.
It's taken me about 5 years to get him to this size. But that is with about the first two years without pellets. Only shrimp and bloodworms. Definitely rewarding to grow out a slow grower like an NTT though! The 210 came with an Eheim 2260, so that will be incorporated into the 210. In the meantime i'm using some of the ceramic media that came with it to fill up the C-360.
