Sounds like various forms of micro-algae and maybe even some small truncates or sponges. They will neither harm nor hurt you tank. They do add some nice color and variety though.

What are your tank specs? Size, lighting, livestock?

29 gallon eclipse, 2 percula clowns, 1 firetail fish, 1 orange tail damsel, 1 green mandarin, and one scooter blenny who is dying.. ( very skinny, and just sit there instead of running around).

Live rock is very porous coral skeletons that are the home to millions of bacteria and the calcium in live rock also acts as a pH buffer for the tank.

Other rock doesn't contain this buffering and also some rock may have the opposite effect and hurt your pH.

I'd monitor your pH if you are having trouble maintaing it I'd remove the black rock. The Lava rock should be fine.


The Scooter and the Mandarin are competing for the same food source. Amphipods(small inverts in the tank) Even in a well aged 29 gal I'd doubt you have the food supply for both of them. I recommend you find a home for both of them. I wouldn't recommend either for a tank less than 55 gal with good amount of live rock.

I keep a mandarin in my 55. I also stocked the tank with Amphipods in my refugium. You can get Amphipods here www.ipsf.com

I checked my pH and it was at 8.0 to 8.2 I guess it is alrite. I have a piece of anemony and it doesn't seem to bloom as big as it used to be. It was a lot bigger in my other tank. what can I do to make it bigger? THe base has expanded about 7 inches which is bigger when it was in my old tank (4 inch) but the tentacle are not big. what is its problem?

Water quality and water flow have the biggest impact on Anenomes. The most drastic changes in my Anenome is when his water flow is diverted.

Are you using Filtered water?

I have a wet/dry filter system and I have two wave maker in my tank so filtration and water flow is not a problem... I think. The thing is my anemony used to attached itself to a piece of live rock I had. but since I moved him into my new tank. he detached himself and flow around and it is on the front of my tank. I don't know if I should move it to a place with more water flow or should I leave him therE? I heard that they move whereever they like right?

Just how long is your tank going? The purple is corraling alge is a calcium based alge and the desired alge that people want. Purple wavy things though could you get a pic? Does it look like this http://www.globaldialog.com/~jrice/algae_page/mesophyllum.htm if so its just another type of corraline and harmless. If not try to get that pic. The dark green and red is it slimy when you touch it? Does it blow around easy when you wave your hand over it? If so theres a good chance it would be cyanobacteria. This is a bad nuciance alge that you don't want and is very hard to get rid of. http://www.reefs.org/hhfaq/pages/picture_pages/faq_cyano.html.. Several things can cause this overfeeding, hi nitrates, old lighting, low circulation, phosphates and silicates. It will cover everything and become an nusiance. It also can cover corals and such and suffocate them.

As for your 29 gall your actually over stocked. Maby for the 29 you could have the 2 clowns and maby one small fish like a goby of some type but no more than that. A good rule for saltwater is 1 inch per 5 gall where some after they get exp go with 1 inch per 3 gall. You can't stock sw like you can fw. Saltwater actually holds less oxygen so you should go with less fish. Get the mandarin and scooter out, they eat pods very few of them will eat frozen foods and need live. I wouldnt reccomend a mandarin in anything less then a 55 if even, and they need a well established tank of at least a year before being introduced. The scooter has the same feeding habits not quite as bad but still need a lot of critters to eat. They are both in the dragonette family even though the scooters are sold as blennys they are not. For one mandarin you should have at least 80 lbs of live established rock for it to survive properly and even then they can wipe out the population quite a bit.

Lava rock isnt quite the first choice for reefs, I've seen it used for fish only. Depending on where it came from it could contain minerals or possibley metals that can go into the aquarium. If you can't afford lr a good choice is lace rock. It can be found at landscaping stores, its cheap and safe for sw tanks. Your best bet is to get that and seed it with a piece or 2 of lr. As far as the unknown black rock get it out if not sure what it is. If your careful you can scrape the feather dusters off carefully they will reattach themselves somewhere else.

Your pH can come up a bit best range is 8.2-8.4 for a sw tank. Also alkalinity will play a big role in how your pH is maintained they work together. Your alkalinity should be at 9-12 dkh. When your alk drops it will drop your pH.

How long have you had your anenome? What kind of lighting is on the tank? How are your water parameters amm, nitrite, nitrate, pH, alk any of them can affect and anemone. They need perfect water quality and bright light to stay alive. They will move on there own he may just be looking for a place he likes also.
