29g pea puffer tank. 12 puffers or 6?
So I have a 29 gallon tank that I will be setting up for pea puffers. I intend on it being heavily planted like 300 to 400 dollars worth of plants and will have the tank run a few months with shrimp, snails, and blackworms. I know they are messy eaters and intend to do frequent water changes as well as plenty of overfiltration. My question is how many should I add? I want a good happy shoal and I know 6 is minimum but I wanna know what you guys with experience recommend. I've considered having ottos to help with any algae but I will keep it species only if It means more peas. What do you guys think?
