Long over due update.
....
-Currently I have a Aptasia outbreak in my DT which I plan on getting peppermint shrimp and maybe a file fish to help with.
-I have a small algae outbreak in the DT mainly on the sand and a few rocks, which should go away after a few water changes. If it doesn't go away completely after that then I will go 3 days with lights off and 4 days with 2 channels of blue LEDs on until the ATS has had enough time to sucked up enough of the nutrients that the algae goes away.
-Also to help with algae I need to get a few more snails and hermits to help keep the glass, rocks and sand cleaned.
Tanks always keep us busy eh?
So you have apatsia. I hate those ugly pests.
I've had aptasia over the years. Never tried pepermint shrimps but I did once get a Copperband butterfy and he polished the Aptasia clean (Then he died a year later since he had nothing to eat, and it appears that is all he would eat).
You have to have some luck with Copperbands since not all will survive long enough to learn to eat aptasia. Some like a 2nd copperband I got learned to also eat frozen.
Interesting that you mention aptasia since I got few starting in my tank.
I have no appetite for a new fish after I tried a Powder Blue tank (got ich) died few weeks later.
So I decided to try
AptasiaX. Really surprised how well the stuff works.
You get a bottle of (harmless liquid. Harmless to Corals/Fish). A syringe and two tips. You fill syringe, and squirt the liquid into aptasia's mouth. They don't retract and gobble the stuff up. 5 minutes later it imploded and it gone.
But you have to be able to reach the apatasia in hard to reach places. So I exteneded the feeder with a airline (between Syringe and tip). Addded a bendable stick and am killing them off one by one.
Bottle is good for about 100 aptasia.
This might help you speed up the Extermination. At least get the big guys (before they spread more spores). Let the peppermint work on the small hard to reach ones.
