tang or herbivore suggestion

Anyone have any suggestions for a small tang or herbivore that will pick at rocks and swim in the water column.

I have a 75gal with soft and sps corals. Fish bangi cardinal, 3 chromis and lawnmower blenny.
CUC
feather duster

Any suggestions would be great. the tank is 6 months old

 

the lawnmower blenny should be eating the algae, if he isnt then it might be slime algae, and thats not really algae its a single celled type of thing i dont know all the specifics. but i think a tang would be fine.

 

Cyano is bacteria, rather than an algae. But a lawnmower blenny will not always algae. A tang would do the job. But they get pretty big.

 

if the lawnmower wont eat the algae, the tang might not as well, lawnmower blennies are known for clearing a tank of algae, hence the name lawnmower. if hes not eating it then its probably vyano like you said. and then theres a different problem like dead spots of high nitrates and what not.

 

A coral beauty will also graze the rocks for algae, but then you have the chance of clam nipping(if you have one). I would suggest adding to your CUC. Some snails will eat cyano.

 

That's true.

If it is cyano bacteria then what you want to do is add to your CUC and also get rid of dead spots. Cyano bacteria thrives where there is low to no water flow. Check your tank for these "dead-spots" and move your powerheads, accordingly.

 

if it is a reef tank i dont suggest getting any angel, with coral they are pretty much 50/50 they may nip they may not. also if you have a major algae problem an angel wont get rid of it they arent known algae grazers

 

CB will eat algae, but not cyano. So that was not a good recommendation for this occasion.

 

coral beauty's are omnivores not herbivores, they eat meaty food as well as algae. if you had a big algae problem why would you get a coral beauty instead of a tang whos sole food source is algae?

 

..I already corrected myself. Let it go. I also suggested a tang, but fish are not what is needed in this situation.

OP needs to adjust their powerheads and/or add to their cuc with some snails.
