Coral issues:

[REBridges]

So guys I have a small issue...From some reason some of my corals stopped opening up all the way, while other corals have increased their size and beauty ten-fold. My zoa's, and kenya tree for example arent opening like normal. The kenya tree almost looks like its being eaten away at the bottom and has started to slump over. My blasto's for example have tripled in size more than normal and look totally healthy and beautiful. Any idea what could be occuring w/o knowing the water parameters just yet?


As soon as I test my water parameters I will give the details of what they are....however, can anyone speculate what could be the issue?

Thanks!

What kind of lighting? Change in flow? Check for pests? Has the kenya started dropping branches?

Not sure how often you do water changes, but when things start to look funny in our 240, ie: zoas not opening up or leathers staying closed all the time, we do a small change not a big one, but just enough for the corals to get their nutrients back and everybody is happy again.

i agree with both comments above, there are nudibranchs that look just like the coral they eat, so you may check for those on the kenya tree. like eve said, small frequent water changes can make a huge difference.

Thanks guys for the help. I havent changed the flow of water, and the kenya tree hasnt dropped any branches. I've looked for pests, but I'll look harder. My lighting is 55w 10,000k T5 Power compact lamps. I did a water change right at a week ago. Should I do multiple changes this week? Or should I do little by little and see if there is a change

You may want to check for pests at night with a red light and a magnifying glass. Alternatively, pull out the corals and give them a good dip in pest killer. Or both!

Sometimes just a particular frag or colony of zoas may not do well. How long have you had them? Are all of your zoas looking sad? What kind ? Pics?

I've had some success with dosing Iodine. What supplements are you adding, if any?

[REBridges]

I will check out the tank shortly with my red light. Not all the zoa's look bad. I have dosed with iodine. I have been putting in all your basic trace elements.

Are you testing "all your basic trace elements"? If not, you're much safer to go the water change route.

sometimes the things that you least expect can be munchin on your zoas, like those evil, little white starfish! good luck

What has your temperature been this last week?
