lionfish tank

is this to much for a 40 gallon breeder tank?

Dendrochirus barberi
Dendrochirus zebra
Dendrochirus biocellatus
Hypodytes rubripinnis (pair)

 

well since they are mostly dwarf lions size wise i dont think they would be too big, Mixing that many different species in that small a tank could spell disaster, I have two lionfish in my 120 gallon a black volatole, and a smaller antennata, they stay far away from each other.

 

You will need a massive skimmer because all those fish are messy, and from what I've gathered:
D. Zebra will fight with other lions often
D. Biocellatus and H. Rubripinnis are both bottom dwellers (fight waiting to happen
D. Biocellatus and H. Rubripinnis would need basically no rocks for all 3 to fit, which is a problem since D. Zebra and D. Barberi like lots of rock
All are carnivorous, so depending on their personality, there could be injuries at feeding time
D. Zebra could get big enough to eat all but D. Barberi
Male lions will fight (I.E. male D. Barberi and the rest females)
D. Zebra gets 7", D. Barberi gets 7", D. Biocellatus gets 4", each H. Rubripinnis gets 4", Total= 26" of (very messy) fish [generally speaking, 1" per 3-4 gallons is recommended] with no chance for a CuC.

IMO, you'd be slowly killing your fish with stress and need to do massive water changes (which lions are sensitive to) every week to even have a slim chance of keeping unhappy, dirty fish.
