I know this doesn't belong here it belongs but for some reason it won't allow me to start a thread in the brakish section. Anywyays, I really am in love with puffers and really really want one. Right now my freshwater tank is cycling with fancy guppies. I have 2 males and 4 females in a 20g tank. After it was cycled I was wondering if I could put a dwarf puffer. I know they are aggresive and will nip at other fish but aren't they poor swimmers? How will it ever catch up to a guppy. Which type of puffer would I have the best odds with in a community tank, dwarf, green spotted, or figure 8?
