I have a large amount of green hair algae in my 46 gallon tank. water par are all good and stable. tank has been set up for 6-7 months. filled with 1 crocea, derasa, and maxima clam. multiple lps corals. 2-96 watt pc's 150 watt 14k hqi. wondering if i can add a lawnmower blenny to handle the algae but i really want to know if one will get along with my sandsiffting goby, (not sure actuall name similar to diamond goby). anything helps.

I would not know about a tank that size but it the 600+ that my mall has they have two lawnmowers and about 10 Sand Sifting Gobies and with my many observations have never seen a problem.

If you are considering getting a tang in the future, this may be the time to do it. He'd have it cleaned up for you in no time.

are there any small tangs that you could put into a 29gallon for a short time period until they get too large? do tangs eat corals?

[aquasalt]

Tangs do not eat corals; they graze in the wild. I have seen tangs in nanos but I certainly would not endorse that action! In fact godzilla may want to avoid tangs as well given the size of his tank.

I have a similar situation. I have a green hair algae problem in my FOWLR tank. I have a puffer and a trigger so I am limited to clean-up crew. I bought a lawnmower blenny to help with the algae. I guess he's on strike because he has no desire for the green stuff. He munches other types of algae like on the glass and fake corals I have. Then I tried a fox face because I was told and have read they are good for eating algae. Same deal he is more interested in the meaty food I feed my trigger and valentini puffer. As a last resort hoping the trigger won't eat him, I recently bought a pin cushion sea urchin. That thing cleans up house. Almost all the green hair algae is gone and the fish leave it alone (SO FAR).

I would recommend a sea urchin, but I am not sure if they will munch on your corals or not. I have read mixed feelings about that. Good luck.
