I have a 75 gallon with 2 C360's and a 600GPH powerhead coming on during the day to blow the detrius up off the sand (black tahitian moon sand). I have about 100 lbs of rock (lots of caves, etc) and have java fern, swords, and anubias. I dose every other day or so (whenever I remember to) with Flourish excell. I have a Nova Extreme T5 lighting (108 watts). I do not run a heater as my temps stay at 79-81 degrees. My water readings are always 8.2ph, 0 ammonia, 0 nitrite, and 0-10 nitrate...I am not good with water changes (I usually only do them once every 2 weeks or so and the water still has those parameters when I change them). I have a high stock load, and have been lucky so far I think:
2 Red Zebras - 1M and 1F (2 females died awhile back) - the male has the middle of the tank staked out and has went toe to toe with each Kenyi
4 Red Top Zebras - 1M and 3F
3 Kenyi - 2M and 1F - each Male has a side of the tank staked out as his own cave
3 Demasoni - 1M and 2F (I had a lot more, but lost a lot when I first put them in...they just disappeared)
3 Mangainos - unsexed at the moment
4 Yellow Labs - 1M and 3F
I know I have a lot of different species, and I might get rid of the Kenyi and the Red Zebras, but I like the Orange colors of the RZ's. The Kenyi were a mistake to get plain and simple - the only way I can get any of the fish out is if I totally take the tank down (have tried catching them, but no luck). I have not had any crossbreading going on yet......my labs tend to hide, being the Kenyi and the RZ's are so aggressive...
