Thanks guys! I'll keep you posted on the little one. The 55 looses about a gallon a day due to it being so dang dry here, so I'm constantly dumping more water in it. He's gotten really good at sniping the mosquito larva out of the dispenser before the other fish get at it too. I did have him in his own ten that was changed out a little under once a week but he just didn't seem to get any bigger. So I threw him in the big one. It was like a month later I realized he'd grown lol. He's finally bigger than my neon's.
Feel free to message me any questions, I'll try to help the best I can!
