| I would rather put French either bigger or smaller than Blu-face. Being equal size means more competition and more confrontations.
Just as precaution, try to have large, clear plastic container w/ lots of holes which can be hung inside of tank (Superking Filter Box or Lee Product, bigger the better or even large clear Plastic Carbon Jar). Use this container to house the new fish for few days after acclimation. This way new fish can really adjust to your water w/o being bossed around (stress factor which can weaken and kill fish or actual physical attack)) by Blue face. Do let him go in the middle of night w/o any light. Hopefully this will give French( or new any arrival) little edge. Have introduced tangs and angels, groupers using this method w/ great results rather than just putting new arrival straight into the tank.
Next time, should consider adding them at the same time whenever possible, angels w/ angels, tangs w/ tangs, etc.
Good Luck!! |
