I have a new baby Aro about 2 inches long in a 55 gal.I lost my last Aro to what I thought was ICh.(rubbed on glass till a soar developed slowly died).My tank now is 82f & has more airation.Now awhile back I added coral because my water ph was too low. Now its about 7.6 & I understand Aro's like water slightly more acidic. The fish is doing ok but I was told over time it might effect the fish.should I slowly remove the glavel/coral until it balances out? My tank:55gal lg aqua clear double air pump.I do regular water changes & I'm feeding sticks flakes & dried plankton & pro for water. I want to raise my Aro to adult.(will get 180 when time) beside the ph any advice would be apreciated. I posted short video at www.youtube.com/L's baby Arowowana if interested.
