How many gobies?

[xDestro]

I want to get a 20 gallon long brackish setup with rock decor and sand and crushed coral for substrate, the whole idea was to get a figure 8 puffer but I want at least a little variety so bumblebee gobys are what I found would be best so how many do you think I could have? I was gonna say at least 10 but I'm still new to this whole fishkeeping

Even the figures 8 puffer is the most peaceful puffer but it's not guarantee it will leave other tank mates alone, especially 20G is quite small to hold a puffer + 10 other tank mates. If you setup an bigger tank than you might have more luck mixing with other species.

forget the goby just keep it as a solo f8 puffer tank lol
well thats what i would do anyways.

I've never kept puffers but I wouldnt trust any kind with other fish, maybe something bigger and faster than them thought but those little bumble bee gobies probably wouldnt fair well
