i currently have a skunk cleaner a cbs a clownfish and a frogsprawn coral in my 75 gal reef left over since my filter returned popped off the pvc and drained my whole tank in my living room a couple months ago...tomorrow i plan on ordering a yellow tang lawnmower blennie and six line wrasse from live aquaria and i should get them by tuesday i no eventually the tang will outgrow but will it be ok to introduce all 3 at once? i have never introduced more then one fish at once so just wondering if it will mess with my parameters
