i'll post some pics and i did add all them at once. but a cycle is not needed in this tank. it was well seeded enough with the used filter, plants, driftwood, and rocks from another tank. i've had about 20 guppies my petricola cat and loaches in it for a week with no spike in ammonia or anything. and as for the one big school, i've always loved neons but never had a big enough tank availible to do a school like i wanted. in reality i went to my lfs looking at getting 50 neons BUT reality kicked in and had to settle with 30 lol. i was tempted to do both the standard and black neons but the lack of red on the black neons turned me away from them.
