This post makes me so incredibly happy! Well done and bravo to you for the tank upgrade!
The difference in the fish is quite astounding isn't it? Congrats
Now just remember to keep up with those water changes and maintenance
Also when you add the moor to join yours in the 55 gallon tank, just keep an eye on the water quality in case the extra poo/food cause any mini spikes with the ammonia or nitrite or nitrate
Would love to see photo's once you have them both settled
