new 75 cycle

[fish boy]

i just got a new 75 gal tank anf i hav to cycle it and i read a good rule is to add 1 damisel for every 5 gallons sothat would be like 15 damisels my question is if i have 15 damisels and i keep them in after the cycle will they bother my 5 inch porcupine puffer

Don't use damsels for the sole purpose of cycling a tank. You can use a couple of pieces of uncooked shrimp from the grocery store. This will work just as well as the damsels. If your planning on keeping the damsels, then you could add a few. But why have 15 damsels?? I've never had that many, but I could only imagine all the fighting between them that would take place... Use the shrimp, if you wanna have a couple of damsels FOREVER, then its alright to add them a couple of days after you have the tank going... I'm sure the damsels would be fine with the puffer(untill the puffer got big enough to eat them~!)

The Damsels won't bother the puffer, but when it gets big enough, it will eat the damsels no doubt. It should be fun to watch though!

Better off investing in some good live rock rather than damsels. If you want some "nice" damsels rather than "mean" get some green chromises. A shoal of 6 or 7 would look nice.
