Hello:

I got a male pumpkin seed (my daughter named it Sunny) and have been trying to get a female.

 

I tried a couple of times, but as soon as I put new pumpkinSeed in, Sunny will try to mate it or harass it if its a male. Next day the new fish just die.

 

Is is because new fish is stressed and further harassment from Sunny caused it to die?

 

Or could there be something wrong in my transporting a caught fish into my tank? I gave it a couple of hours to avoid the temperature shock.

Could you post the gallons and dimensions of your tank?  I have not found keeping pairs of certain Lepomis species to go very well unless you have a huge tank or tons of structure.   Certain species, including L. gibbosus, are very territorial.

Regardless of tank size, install a partition providing a refuge of "female" from male. Make so female can get into locations where she does not see the male if she wants. For a Pumpkinseed, the male needs on about 12" x 12" to operate if you desire a spawn.

Pumpkinseed males are aggressive so you’ll need a large tank (like Jason L recommends) because a female needs a hiding place for safety. Consider a 1 small male-to several larger females combo to spread out his aggression. If you want to breed them you’ll have to put them thru a cold spell temperature-wise for a couple of weeks. This diverts the food they eat from growth to egg or sperm production. After the cold treatment gradually increase the water temp and lighting to simulate springtime. If he pairs with a mate take the other females out after the spawn then take the mother out as well. Good Luck.

Centrarchid..I was offering a suggestion from past experience, not trying to impress anyone. Your suggestion works for me.

Pumpkinseed Sunfish do not form pairs. All females better taken out at once. Simulation of winter / cool season followed by spring warm up not required as a promoter of reproduction. I like to have information simple as can be yet accurate, otherwise suggested cares regimes get into realm of voodoo where they are hard to replicate.

Thank you for such helpful advice. I don't know why I myself could not think of it. :biggrin:
