I currently have 5 bumblee gobys, 5 dwarf (pygmy) puffers, 4 khuli loaches, 5 cardinal tetras, 2 otos and a fire belly newt. Ive been doing some research on figure 8 puffers and some people say they have been well behaved while others say they are extremly eggresive. I know they should b fine with the bumblebees and if the tetras get nipped i wouldnt mind giving them away to my friend. the main thing i dont want to happen is my dwarfs gettin eaten or the fire bely newt. can i just have some help please and opinions on what u think i shud do if i want to base my tank arround the figure 8. ps i have the freshwater gobys and i have read that figure 8's live in freshwater but do better in brackish, but i am still going to buy it, jus clearin that up because people on this site jump down peoples throats before actualy helping. but thank u guys!
