me and a friend were fishing today and i thought one of the fish we got looked pretty cool so i took it home and setup a tank for him most of the water in the tank is from the creek the other say 40% is from my other established cichlid tank so can i keep them and how many times should i turn the water since they came from a creek? how big do they get??

well its just for a day or two but rite now its in a 27 gal...i have to free up my 75...how big can these fish get??

Do you have a photo of the fish?? the common name chub is a lot like Minnow...There are a bunch of them and common names vary from locality to locality. Getting a correct ID of the fish will help in giving you a better idea of how to care for it or anything else about it.
 
You don't neccisarily need a ton of flow. I have owned them before and its more important to keep good cold water. Cold water isn't really neccisary but mine enjoyed it more when the water was cold. And anything beyond that really depends on the speices.

It should be remembered that there is a direct relationship between temp and Dissolved oxygen (DO). At lower temps there is more oxygen than when the temp is higher. Stream / creek / river fishes generally require higher oxygen intake than lets say a lake type fish. Raising the flow and agitation of the surface water will increase DO content in warmer water.

What you are seeing when you see the fish happier in colder water than in warm is often it is receiving more oxygen in the cold water than it is in the warmer water. Species is really a necessity to know so that one knows the lethal temp of the fish as well as the level of oxygen it will require. One can keep many "coldwater" fish in a warmer temp tank as long as this relationship with temp, oxygen, and flow / agitation is understood.

Ah yea I forgot about all that. This is true so I guess a faster current would be neccisary if keeping in warmer water.

ok ill try and get a pic for you. thanks alot for the DO lesson i didnt know there was more oxygen in cold water. i have a hang on filter w/biowheel,air stone and a power head making a heavy ripple on the surface that should be alot of oxygen right? and the temp is roughly 63 (worthless themometer). but i know the room temp is 68F so the water should be like 10 or so less right? and i was in the creek it came from and it wasent really really cold.
 
I had a hard time keeping a chub in 70 deg water. I hope yours makes it.
 
well its been 3 days and they seem to be fine theyr breathing slightly heavy but i think theyr just not used to the tank yet...how big do they get??
