If i were you i would get smaller cichlids if you only have a 45 gallon jd's require alot of space to keep them happy and healthy it would be cruel to keep them in an environment with inadequate space i had a jd in a 55 gallon to let him grow until i could introduce him into my 100 gal he quickly outgrew the 55 and got in alot of scraps with smaller cichlids. What you need to remember is a jd is a cichlid and all cichlids are aggressive naturally even "peaceful" cichlids are only as peaceful as a cichlid can get. Cichlids also require alot of space as they are very territorial especially larger species like the jd if placed in a tank too small they won't have the intriguing personalities we all love about them because they will be unhappy having to share there territory in such a small space. There are many smaller cichlid species that could be much easier to sustain in a 45 gal tank and be much more happy in one than a jd would be. Cichlids are also social fish so you would not have much room for tank Mates for a jd. I really suggest you look for smaller species there are many beautiful and just as interesting smaller cichlids you could find and you can keep more of them! if you want a very interesting cichlid do some research on shell dwellers i find them to be some of the most interesting cichlids and they would be perfect in a 45.
