Im sure plenty of you guys know this but I never knew how much of a difference clean water would make. I had a texas and green texas breed in my 75 gallon. The mom died but I left them with their dad for a week then siphoned them into my 40 gallon that had some convict fry. 2 weeks later I found 3 fry still in the 75 and they were larger than the ones in the 40 gallon. For those 2 weeks the 3 fry, I call them the 3 musketeers, had nothing to eat except the algae thats growing on the back glass while the ones in the 40 gallon are getting 2-3 feedings of baby brine shrimp and 50% WC every 2-3 days. Maybe I need to up my water changes in the 40 but I'm amazed at how I had to do nothing to the 3 musketeers and they're still growing.
