Wes sent me 4 green Hoplias lacerdae 3 years ago in Aug-Sept 2015 as a surprise. They were ~4".
They have been easy to feed in 240 gal taking sinking and floating pellets and thawed fish. About a year ago they went into the 4500 gal, feeding on the same but not competing too well because the bowfin took it thoroughly upon itself to show the wolves that they are not welcome here every time they bump into each other, so they stay away from the bowfin and from prime feeding spots but thankfully the bowfin doesn't seek them out throughout the whole tank.
The bowfin took one eye out of one wolf. The wolves had been growing thin so now they remain the only fish in the 4500 gal that still get hand fed thawed fish off tongs. The bowfin is about 20"-21", the wolves are about 16"-17".
Other than that, they appear peaceful and do not initiate any trouble of their own accord. They do not quarrel among themselves, not that I noticed and not that that would be memorable.
We have just lost one for no obvious reason, so I know their current size.
