Iím setting up a 40 gal (breeder) reef tank. I really like rabbit fish and think theyíre awesome but obviously canít put on in a tank that small. I think they look cool, I like how they eat algae, and think the spines for self defense are cool.

What are some alternatives for a 40 gal tank?

Yellow tang.



I thought yellow tangs needed at least 100 gallons?

I have a yellow and a blue in a 60g, they were the last two adds, were QT together and put in the DT at same time. The yellow was 2" and the blue was 1".

They share the DT with an Anthais, a Gramma, a mandarin and a mated pair of black clowns.


The only issue I will face sometime in the future is increasing tank size.

Thatís the issue - I cant increase the tank size. Otherwise Iíd definitely be throwing in a blue tang and a Rabbitfish. Shame I canít get a bigger system. :(

If you are looking for algae control emerald crabs, urchins, and snails work well in smaller tanks. Depending on the types of coral you are keeping blennies are a possible alternative.

Iím mainly looking for aesthetics over their algae control.

Yellow Tang 100 gallon
Blue (assuming a Blue Hippo) 240 gallon
Here is a guide (http://www.reefcentral.com/forums/showthread.php?t=1946079)

The issue for tangs is more about swimming room (length of tank) and less about volume.

I have a yellow tang and a Kole's tang in a 90. They seem healthy and happy. Neither is my original fish but I've only replaced them once in 21 years. Pygmy angels OTOH (smaller fish) seem to live only 6 years.
IIRC these were the smallest eventual-size tangs available to me at the LFSs. Although they are both called tangs their food niches are very different and they don't compete with each other.

Maybe a flameback or cherub angel? Both have more blue that yellow, but have that flat shape like rabbit fish or tangs. They are also herbivores. I had a cherub for over 7 years in a 30g and it was happy with the space. It liked to move in between the rock work, so it made much better use of the space than a fish that just swims end to end. This behavior is one of the things I like about the dwarf angels.
