Finally adding new fish to the 300! I am looking to add at least 15 more fish to this tank for multiple reasons. Having African cichlids over the last 30 years I have certainly benefited from having more fish in the tank vs. less. It comes down to more fish equals less aggression, plain and simple. Between the constant drip/auto water change system and Aquaponics, the nitrates remain basically undetectable. This has worked flawlessly for me over the years and I look forward to having a higher fish count again. More updates to follow.
