Kois are sucking on my Female BP's anal tube..
I know kois arent suppose to be in there but its just for now until early summer, is this normal or this has to be stopped? They keep on sucking at the anal tube where she is currently pregnant (which i think she is) and her top fins are showign at the surface.

Well, the first and foremost problem I see here is that you have fish that need 2 drastically different temperatures to be healthy and to survive. BP's need tropical temps, 78 - 80, and koi need cold water temps of 65 - 67. It is very likely that your fish are acting odd because they are struggling to survive in the wrong temperatures.

You haven't provided us with much information... so there isn't going to be much else we can offer for help at this point. We need to know a number of things before we can make any other suggestions:
How big is the tank?
How long has it been set up?
Water params for ammonia, nitrite, nitrate, and pH?
How often are you doing water changes? How much water each time?
When did you perform the last one?
What foods are you offering? How much and how often?
What kind of filtration are you using? (make and model numbers are most helpful) What media is in it?
Do you have a quarantine tank?
How many fish of each species are in the tank?
And most importantly in this situation, what is your water temp?

Please tell us as much as you can about your tank. Those water test results are also very important, and exact numbers are the only thing we can work with, and all of those tests are equally as important, so excluding 1 or 2 of them ends up telling us very little. Please post exact numbers for each, and let us know what kind of test kits you've used. Test strips are useless, they don't give accurate results. Liquid test kits are the most practical and accurate unless you are using electronic meters.
