I have a 90g that I am setting up as a Walstad type tank and would like to keep Lined Topminnows, Eastern Mudminnows, and Bluespotted Sunfish.  Any suggestions as to the number of each species? I have heard varying reports about the aggressiveness of the topminnows towards each other.  Any other problems you can see with this tank?  Worry a little about the topminnows being too greedy with the food for the others.  Thanks

I think your tank sound like a fun experiment. Start with small mudminnows and I think it could definitely work. I have a 25 Walsted setup and a 75 that runs with lots of plant (but also a cannister) so I am extrapolating a bit. But with that caveat;

8 Enneacanthus
8 Fundulus (you will have some losses maybe but they mostly only pick on each other)
4 mudminnows (again I would say start small)

Thanks, I had been thinking 8 Fundulus, 4 Enneacanthus, and 3-4 mudminnows so it is good to know I'm not too far off.  Any suggestions on M/F ratios or just let them sort themselves out on their own? (Meaning take what I can get.)
