| That sounds like a good idea. if you didn't want a betta, the best you could hope for would be 5 neons and that wouldn't exactly make the tank interesting!
as MrWaxhead has said, any of the live-bearers would rapidly outbreed the tank, although that, in itself, would be a point of interest to the students, (my daughter spends hours just finding the new arrivals in our tanks), and it wouldn't be difficult to find new homes for the fry! (Could even be a good way of getting the students into fish keeping properly). Bear in mind that the tank would need a great deal of maintenance, considering that most schools are closed at weekends etc, this could be a problem.
plants are definitely a good idea whatever you put in the tank, because of their water cleaning abilities as well as hiding places for the fish. As stated, a 5 gallon tank could not go for long without maintenance, even with live plants.
Either suggestion has merits, both have drawbacks. It's your call. Enjoy! |
