jack dempsey?

hi everyone.

ive kept fish before, breed angels, and kept discus for a while but stopped around my senior year of high school( got a offer for my setup i couldnt refuse)
well anyways im now in my freshman year of college(only 2 year). ive gotten a apartment for my 2nd year of college that allows fish tanks, so im starting my research now. so i have a couple questions.

first, i had oscars before and loved them to death, but ive decided to try something a bit more pleasing to the eye, dont get me wrong i loved me without end but the first comment i always got, was man that this is one big ugly fish:silly:, from a personailty point of view how to the jacks compare?

second, how long would a baby(1-2inch) JD do well in a 29, i would like to get a baby and keep it at school with me, but the largest im allowed is a 29, i have a 75 sitting at home that it would be moved into as soon as it outgrew the 29, it will be the only fish in the tank, unless i see its skiddish then i may get a few dither fish to make it feel better till its larger. but how long would you give it till it outgrows the 29, ill be in the apartment rougly 7-8 months, and then im done with college. off course if at anytime i see he's getting to large for the 29 i can move him to the 75 within 30minutes.

and finally, ive looked at the blues and the regulars, and from reading sounds like the blue is more fragile but also grows slower, i keep my tanks spotless and clean(something i got from keeping discus) and usually run a oversized canister filter on my tanks as well. are the blues real fragile, or is it just in poor conditions? should i keep with the regular dempsey, if so is their traights i can look for, for a individual that will have real nice color on them?

thanks for your help

thanks for the help guys, my plans are probably to keep him or her in the 29 till she reaches 5-6-7inch or until i feel that their comfortable and healthy. i started my baby oscar in the 75, and wasnt thrilled with it, it was to hard to keep a close eye on the oscar and he missed alot of food at feeding time. especially if i get a electric i wanna be able to keep a very close eye on them.

i was reading that a uv sterilizer is a good idea with the blue, can anyone tell me about these, ive heard of them, but never used one myself? and is it a good idea?
