1 powder blue tang
2 clown fish
1 coral beauty
1 hawian hawkfish
2 spikefin gobies
1 tear drop butterflyfish and
1 orchid dottyback?
And what would be the MINIMUM size tank, none of the stupid answers like 250g or 10g only experienced aquarium owners
Answers:
you cant in a 30, the reason is the powder blue. They are not small fishes, and need a good sized tank of 70 gallons, dont forget they are always moving and would like extra open swimming room, so a 30 cant provide them that.
The others will be fine in a 55-75 gallon, with plenty of live rock.
The best thing is to get at least 75 gallons if you plan on getting the tang.
I know I'll get dinged for saying this because you said 250 gallons was stupid, but, if you want a truthful answer, 250 gallons honestly would be what you need to get. You want to buy the tank for the adult size of the fish, not only to save you money, but also to provide adequate housing so that they grow well and are not stunted.
Requirements:
Tang:70
Clown:20
Hawkfish:30
goby:10
butterfly:70
dottyback:30
This equals 260.
