What (if any) type would be good in a 40B (at least for awhile) If I recall, I think there were some species of dwarfs that were solitary... Also, how long could a black piranha (peru) be kept (I think they grow slow) in a 40?
If they don't have enough respect for the fish to treat it properly, they should stick with guppies.even a small rhom will do. Most people don't keep them long enough for them to outgrow the tank
I don't think it's a lack of respect. people think they're getting an aggressive, active fish. Most rhoms just sit in the corner and they get bored with them.If they don't have enough respect for the fish to treat it properly, they should stick with guppies.
