Hi all - I have a 30 gallon tank (30L x 12D x 18H) that is still cycling at the moment, and I've been thinking a lot about what I want to stock it with. I've decided on going with neons, but I had a few questions:

1.)Will regular neons or cardinals school with black neons, or would each type be their own school? I would like to get one school of black neons and one school of either standard neons OR Cardinal tetras, if that would work.

2.)How many would be a good number to have total? I would just split them 50/50 and have two equal schools...I just don't want to overload the tank.

3.)I will also be adding some shrimp, either red cherry or painted fire reds. How much would they affect the number of tetras I can have in there?


I have read a LOT about compatability between neons and shrimp, and it's pretty divided as to whether or not it will work, so I figure I'll give it a whirl and see how it goes. I have a few plants in there now, some fake rocks, and a piece of driftwood with moss tied to it, so there will be places for shrimp to hang out once everything gets going. I wouldn't be adding the shrimp until after having the tank going for a while with the fish in it. If things don't work out, I will get a second tank and make it shrimp-only. Thanks in advance for any input!
