Any suggestions? I will be getting one baby turtle, so something that gets as big as possible for this size pond would be good. I saw on another post someone talked about cichlids. That would be great, I am in south florida so I temperature might be a factor. The pond will be at least 60% shaded.
 
The turtle will make short work of all but the absolutely largest fish as an adult, and as a juvenile will be subject to some serious abuse from aggressive fish. I wouldn't recommend mixing them, sorry.
 
Ive kept them together in the past without incedent. As long as the fish was a decent size, the turtles were not interested. But I know I can't keep koi in there because the pond is too small. I'm thinking of a medium size fish that would be happy in a 90. Can most freshwater fish thrive in a pond?
 
The temp would be the limiting factor, so you may want to track the range and see how warm it gets, and how cool. I know blue spot gouramies will get fairly large, and are peaceful, but active enough to avoid someone cruising with a snack in mind. They are tough fish, and can tolerate some pretty wide temp swings as well.
 
Disregarding (or ignoring) the fact that you want turtles with the fish, a decent sized fish which CAN be outdoors in a pond is the Goldfish. Fancy goldfish cannot handle temperature swings like commons (comets) can so keep that in mind. They get around a foot long. You could get 6-7 Goldfish.
 
Well crabbyjack is in south florida, so he could house a large tropical fish. 90 gallon is a bit small for some of the fish. You could do some pink kissing gouramis they are about the easiest for a pond (among the gouramis and still not that easy), most gouramis are rather slow. Even the pink ones are a little tricky in a pond. My suggestion would be something like 4-5 tinfoil barbs, they are pretty tough and pretty fast. They can handle a florida winter pretty easily. But 90 gals isn't a lot of room for them once they are grown. You could do a number of cichlids is those interest you or you could do different types of catfish but you won't see those guys much.
 
How about establishing a colony of guppies? A nice snack for the turtle, but at the rate that they multiple it would hardly make a dent in the colony.
 
hmmm...I (personally) have never been a fan of keeping tropical fish in a pond but then again, I couldn't if I wanted to!

I do know that many tropical fish couldn't handle the severe temperature swings that a small pond like this one would have. 90 gallons (outdoors) can have drastic temperature changes so I'm just not sure which "tropical fish" could handle the pond life. :confused:
 
You could do some mosquito fish. They breed so rapidly I doubt the turtle could keep caught up. Other than that, what I mentioned before either tinfoils or cichlids (mayan cichlids are somewhat native to Florida and they handle the winters). However, Cory does have a point about the temp fluctuations you may get in that small of a pond. Knowing the summers/winters my guess would be 15 F max on 95% of the days, 20 F the rest. Cory, what do you think of that kind of fluctuation? My big ponds very rarely fluctuate over 10 F.

If you could keep it in the shade in the summers, you could probably make the fluctuation less and of course you would need to cover it at nights in the winter. A 90 gallon pond is a little tough.

I'm not really either except in the case of a large pond. However, a 90 gallon is very limited as far as cold water fish are concerned.
I doubt I would enjoy tropicals in my 1000 gallon pond. The larger one is find (3000 gallons) although I would even like something like 10,000 gallons much better for the tropicals.

How deep is this pond going to be? If it is a deep 90 gallon (like a barrell pond or something) I doubt you would ever see tropicals. They are hard to see from top anyway unless they have a lot of room to swim.
