Hey everyone! I am planning a pond. Not like the waterfall pond I have planned. This one is going to be about 200 gallons. I wanted sticklebacks but I'm not sure for tankmates for them. Everyone says they are aggressive so I'm kinda stumped.
Sticklebacks can be aggressive but only towards their own species. However, as for pond mates for them... That's when you have to be careful as Sticklebacks are very small so even a goldfish could try eating them and then because of the spines you loose two fish in one go.
Minnows and Bullheads if you are trying to keep it all natural. If you want a fish you can see then there are Golden Minnows available from some aquatic centers.
