Avsdragon Posted September 21, 2016 Share Posted September 21, 2016 So I am noticing a small green mossy looking algae starting to grown in my 75g tank. I have reduced the amount of light my lamps are on, reduced the amount of feeding to once a day, and have done a water change several times. I have a black sail fin blenny in their now but he is not touching the stuff. I have been told to get a Lawnmower blenny to eat the green algae. However doing more research i am seeing that putting 2 blennies in the same tank is a bad idea. So would it be beneficial for me to get the lawnmower blenny as well and I have nothing to worry about or is their something else I should be doing to help eliminate this algae growth? Thanks Quote Link to comment Share on other sites More sharing options...
youcallmenny Posted September 21, 2016 Share Posted September 21, 2016 I've heard two blennies are a bad idea. That said, my fat little lawnmower doesn't eat anything except offered food. His name is Jabba and he deserves it. 2 Quote Link to comment Share on other sites More sharing options...
ChrisQ Posted September 22, 2016 Share Posted September 22, 2016 Danger! Will Robinson! Danger! Yeah everything i've read on them (or tried to anyway) there will be blood unless you have a really really large system. It's a shame to because i would have a whole hoard of them if i could. What other fish are in the system with the black sail fin now? 1 Quote Link to comment Share on other sites More sharing options...
youcallmenny Posted September 22, 2016 Share Posted September 22, 2016 As a side note, I've been keeping the lawnmower with a mated pair of scooter blennies. They don't seem to even notice each other. Quote Link to comment Share on other sites More sharing options...
