Are you using RO/DI water? If so, what is the TDS?
Yes. Our TDS is zero.
About two months ago, we had a relatively small hair algae outbreak. Thinking we maybe had phosphates in our water that just wasn't being detected (after all, only a sample of the water gets tested), my boyfriend went ahead and decided to purchase new filters. When he called the company to order them, he ended up just buying a new RO/DI Unit (with new filters of course) because they gave him a "great deal" (I'm sure it really was, but you know how salesmen can be). Now we have an air water ice 4 stage unit. We used to have a 3 stage Aqua FX unit. We mix the RO/DI water with Instant Ocean Reef Crystals. We end up topping it off about one every 2 or 3 days and do a 10-15% water change about every 2 weeks.
What did you try to feed it?
I tried to feed it the following frozen food thawed in its own aquarium water in a cup, then squirted with a syringe into its mouth: Hikari Baby Brine Shrimp, Hikari Brine Shrimp, San Francisco Bay Marine Cuisine. The only foods in the tank are the naturally occurring pods, the de-thawed frozen foods listed above fed every day or every other day, and about a 2x3" dried sheet of Nori Seaweed every 2 or 3 days for the turbo snails and crabs.
How large is the anemone?
As big as it can be, it is about 4 inches across. As small as it has been getting, it is probably only 1.5 inches at its smallest.
How large is the clown?
The Orange Ocellaris is a little closer to 2 inches, MAYBE two inches max but I doubt it and it is hard to tell. The Black Ocellaris is closer to 1.5 inches.
A few other things:
We have a small female Emerald Crab that was hiding in the rocks where the anemone was attached and I think was bugging the Anemone foot. I tried to get her out to put her in the refugium, but she kept going back into the rock. I haven't seen her or the other male emerald crab since (about a week to week and a half ago) and figured they were either molting, mating or both. Then again, I usually work from home but have been working from my mothers house recently as I have been housesitting for her this past week. I go back either tonight or tomorrow. Since my boyfriend is away from the house all day and exhausted at night, the emerald crabs could be coming out and tormenting the anemone, but I would think the anemone would move? I even put extra rubble at the base of the rock, in case it wanted to move down there. That same day I noticed the emerald crab bothering it, I noticed the anemone had moved over slightly. I then went to these forums and read previously existing threads (as to not bug people with my problems if there was already an answer listed) and thought that maybe it wasn't getting enough flow. I then moved it higher up in the tank (borderline between the top and middle third of the tank) and rotated it a hair towards the pump. The tentacles weren't waving like crazy, but just had a slight flow from the current. It also is more exposed and no longer in a corner between two rocks. My boyfriend is taking a picture when he gets home.
This all may be too much information, but I have found on this forum and in this hobby, that God is in the details and that too much information is better than too little information. If it is too much, I sincerely apologize. I tend to give too much information and I am still figuring out how to form appropriate questions and responses on this forum.
Any help anyone has would be very very much appreciated and thank you two so much for responding to my original post!
Maybe I can get one in a few hours? I'll call my boyfriend for the exact specs regarding our RO/DI unit and lights.. just a moment..
hwell: We will see what happens. We attempted to feed it a silverside and it kinda finally grabbed onto it, held it, then the sally lightfoot came and took the silverside away
