I think im going to go with the 125, and put a sump pump in it. I have heard there the most effient, let metance, and most of all the most expensive, and if i ever go to salt water..it would be worth it. I'll probaly get a texas, and a jag, becfause i'll have some other ciclids. I dont know what kinda bottom probaly rock. Put plants? or maybe a lot of rocks, i sell real stone so that owuld be cool any other suggesgtions they have been gerat, and some pics of some golden spectrums, i saw a really nice one @ the pet store but they were sold, also, how aggresive are they also, what is there behavior!d
