I was thinking the trademark orange with white stripe clown fish. But seems like we are back to square one. If in general a pair (male/female) is all I can keep then a small 14 to 20 gallon bio cube with sand and a fake anemone should be enough. The smaller tank will also place more emphasis on just 2 fish, not to mention cost & maintenance should be allot more manageable. Ill probubly even use a sump filter to increase volume and an auto fill tank filled with RO for auto top-off. Of course Im just speculating if it will work as it seems logical, but I obviously have to do more research to avoid big mistakes and not waste my time and money.
I had the larger version of biocube in the past. Lots of corals to =). Two clowns... did fine.
Sump is not necessary but isnt bad idea either. if you manage to Mcgyver the tank to have overflow to sump and return...go for it... I think though if you are going to do that its a waste of money I think for the results.
Still the cost on Bio cube is about 300.00 roughly
Now you add sump
return pump
You are looking closer to 400 now. Add a skimmer you are up over 500.
More bang for your buck here:::
55 gallon 100 bucks
20 gallon tank to be sump (craig list or petco cheap)
Return pump 100
Skimmer 150
Overflow box 100
The prices are so close that I think if you are not going just bio cube...and adding sumps and things... You may as well go the other route that I roughly threw out in suggestion for an alternative.
