i am going to start up a peacock tank i just aquired a 75gallon tank, pine wood cabnet and canopy, 48inch 4x65 orbit light with 4 moonlights made by current usa i need to know what type of light bulbs should i use cause they have a lot of types like what is a 50/50 bulb?? or Actinic bulb?? i think the 10,000k is like sunlight, and what kind of substrate should i use i was thinking of either crushed coral or reefsand, and how many should i stock up with?? the guy at the shop said 18 cuase they will kill eachother off and you can have like a max of 12 in the 75... i'm not sure if he was trying to sell me alot of fish or something... i am also getting confused with haplochromis and peacocks (alanacara or something like that) what kind of filtration would be good?? i was thinking of a power filiter hangon like the marineland penguin 350b or something... wet dry for african cichlids never really worked for me... this is going to be my first real cichlid tank (i dont consider my frontosa, dubois tropheus, calvus tank a real ciclid tank cause i have gravel and clay pots in the tank) and i want it to be awesome... thanks oh and what is good to build caves with?? what type of rock?? i was thinking of texas holey rock or is there anything better?? o and should i even use the moon lights?? will it benifit them or anything?? and the light has two switchs so if its too much light i can cut it in half from 260 watts to 130 watts...
