I'm looking to start a planted 40 gal (could be talked into a 55) tank with longear sunfish. Was wondering opinions on how many I can keep in the tank or maybe suggestions on different sunfish other than longear.

Also suggestions on plants for tank and possibly other species that could keep along side sunfish. I'm from NE (PA) and really want to keep native plants in tank, but have no idea where to start.

Blue spotted are great for a tank that size. Small size and not overly aggressive.

For Longear you'd need to keep a single fish in a tank that size imo. They are fairly aggressive and territorial towards their own species and that's not enough space for the half dozen or so you'd need to diffuse the aggression. Need at least a 75 for this, even bigger would be better.

A single or several fish.  Going the several route, assuming you do not have a backup tank, then go monosex.  Keeping several up to about 4" in such a tank doable.  If you can push the filtration, then a dozen or more better yet.  Keep them out of breeding mode.

Find ways for people not already interested in natives to value them.

How do you sex sunfish?

Controlling for everything except sex, males are more brightly colored once sexual maturity realized.  Assuming Longear Sunfish are your target, males tend to have longer ears as well.  You can also squeeze them for gametes.



Show a picture of fish you are considering.  Make so we can see each fish clearly.

If I'd go the pumpkinseed route could I keep to males in a single 40 gal tank or would I need a male and female?

Also for a planted tank do I need a CO2?

See Centrarchids response from Oct 20 for qty.

No you dont need CO2 for plants
