Im actually goin do just the pea puffers after all the videos from the spotted congo and the pea puffers i have go with the pea puffers as they just a real nice looking puffer and i think if i go with 20-25 of them in a 180 gallon lots of plants and hiding spots i think it be a nice looking tank. Hopefully i will get lucky and have more females than males for from what ive watched is better cant wait to get everything and get it set up. Appreciate all the advice. Been watching vids for days now trying nail down best filter best fish substrate plants lol
