A bushynose still might not work depending on tank size. Whaty is the tank size?
True.. but this is MFK, so I'm assuming a 'small' tank is a sensibly sized 20 or so gallons? If it's not, swap it over for one that is so the kid actually has some room for a few fish
Plenty big enough for a bristlenose. Otos are smaller and also a good choice, but they are a very social fish, so you want to get at least 4 of them. 4x1" Otos, or 1x4" BN
His MFK Uncle is doing his homework to make sure he doesn't end up with an 18" Gibby in said 2ft tank
