I have a ten with a Gold Nugget Plec, two Gold Barbs, two cherry barbs, and a couple Neons. I want to move my betta from my 1 gal at work to this nice planted tank. See any problem?
I would be worried about overstocking that tank. Give the GN his own tank. Ewurm, he's so nice he DESERVES it. Then put the rest of the fish in their own tank.
I could give the GNP his own tank but why? He is only 3" with tail. I could pull the Gold Barbs, they are the biggest fish in the tank. The params are all good.
Depends on the personality of the betta. My betta even attacks the snails in his 2.5 gallon tank. You could divide the tank temporarily and see how he reacts to the other fish, maybe he will get used to them and then you could take the divider out. I have seen bettas in some pretty crazy setups.
