They are sensitive like other tetras so you'll need to wait until your tank has suspassed about 4-6 months from the time it finished cycling. Danios are good fish to begin with. Be careful as they jump.nicklovgren said:i like those neons.....i just googled them
so are there any downfalls to them such as they are dirty or anything like that?
Stick with the males. They are quite too prolific IMO. Kuhlis aren't bad. 4 in a 10 gallons is excellent. Make sure substrate is not sharp as they tend to injure themselves when they bury themselves under them. You'll rarely see the kuhlis unless you can turn on the flashlight in the middle of the night. Also, check the filter to make sure the filter intakes have strainer to prevent them from going inside the filter and possibly killed by the impellor in it.nicklovgren said:how about guppys
