Introduced a green BTA to my tank about a little over a week ago. He looked good for a few days (when I could actually get good views of him) before he decided to wedge himself between two pieces of LR. I might have made the mistake of trying to move him to a different location, because to me that seemed like a pretty un-benefiting spot for him and I wasn't sure if he was going to move.
So I gently scraped him from the rock, placed him in a bowl filled with tank water for a couple of minutes as i looked for a new spot (boyfriend's idea, not mine.. i should have probably not allowed for that), then re-placed him. Next day he was sort of attached upside down at another piece of LR, and I left him alone.
This was like 5 days ago. the past few days he's been looking pretty deflated, but attached. this morning, found him detached and upside down in the sand. I scooped him up and placed him on the side of some LR, and he quickly re-attached. I poked him a bit to see how he felt, and a few of his green tentacles (or whatever you call them) fell off. In appearance, he looks like he has very few tentacles especially in the middle, its kind of just an empty looking spot. He's got some chunky looking purpley stuff hanging off of him, not sure what that is.
I mean, he's not dead yet if he's attaching to objects still, right? :/ Is there still hope? Sorry no pics to show, ill try to get one up when i get my camera from my car.
Also.. he's only about the diameter of a quarter, if not slightly bigger.
I've not experienced purple chunks on my anemones...even dying nems, so I don't know. Sometimes a dying anemone will still have enough reflex to attach but usually not. It's difficult to guess without pictures or even observing earlier behavior.
It's completely normal for a BTA to hide during acclimation. You shouldn't have moved him but hindsight is 20/20. The choices an anemone makes are instinctive...reflex-like, so unless they're headed towards the powerhead (an instinct), it's okay to let them do their thing. (Easier said than done I know.) Moving your nem once didn't help him, but I doubt it killed him either.
It's also unlikely your anemone was significantly suffering from inadequate lighting. True...your current lighting can't provide enough nutrition for a BTA long-term, but your nem didn't starve to death in a week or even 2. Beyond that, most BTA's prefer medium light. Don't get me wrong, I love my dimmable 3 watt LEDS. I highly recommend them. But I have 6 BTA's and they can't tolerate those LEDS higher than 50%. They cringe and posture at 60% and they start to bleach at 70%. So if I were lighting a 14-gallon Nano, I'd get both fluorescent 5500K and 10,000K sunlight/daylight bulbs. I'd start with the 5500K and see how things go. The nem will probably eventually want the 10,000K. I'd use actinics for color too, or I'd get 50/50 bulbs- 1/2 sunlight 1/2 actinic. Minimally, I'd put 75 watts over a nem in a 14-gallon tank but would lean more towards 100 watts with shady overhangs for the nem to get under if he wants. All my BTA’s like the shade as much as they like the light. They live in the shade and they reach out for the light and flow.
Overly friendly clownfish kill acclimating anemones. Inadequate flow will kill an anemone more quickly than inadequate lighting. When one of my anemones starts to mope, flow is usually the culprit. BTA’s need 2 power heads to create an ideal multi-directional current…that may be difficult in a nano. They don’t like to be blasted though either. Flow to a BTA is like air to a human. Buying an anemone that is still acclimating at the LFS is certain disaster. Many anemones are poorly handled during import...having spent many days in total darkness only to be placed beneath direct light…ouch. Spending 24 hours floating in a shipping bag of it’s own waste will kill an anemone. I've had good luck with both drip acclimation and simply temperature acclimating them and putting them directly in the tank so I don't have an opinion either way on that.
FYI for next time: Stressed anemones appreciate water rich in zooplankton. During the last couple months, I’ve reduced my anemones raw-seafood feedings and increased their water’s zooplankton concentration. I can see measurable improvement in their appearance.
Beyond that, your anemone was/is likely stressed by one or several things outlined above…all stressors that may have been overcome had your tank been seasoned. Young unstable tanks kill more stressed-out anemones than anything else. The fact that yours is a Nano reduces the margin of error even more. Try again in a few months with better bulbs, stable water parameters, and bi-directional flow…with an anemone purchased from a trusted source and I bet you and the nem succeed. Me and my 3rd GBTA did...still are. And don’t forget about the zooplakton…not phyto…zoo.
