sea cucumber: A-sexual??

[ophiura]

Well it is a relative, of course, but it is not like the sea apple in terms of toxicity. This cucumber is [probably the most common filter feeder cucumber in the trade.

doesn't look like a worm, at either of the 3 stages of growth. The first and second stage at one time I thought might be a snail but the picture above of the baby looks like a baby cucumber for sure. Haven't made it to the local fish store yet nor have I gotten the babys out yet..... I have a headache, and I am not looking forward to doing this task....hopefully tomorrow.

well, looks like I have 3 different critters in my tank that are not related to each other, the 2nd stage(as I thought it was a stage) is for sure a flat worm, the 3rd stage they are not sure exactly what it is they think some sort of sponge but it is not a worm like the other. I am not happy about any of the creatures taking over my seahorses tank. Tomorrow its going to be deep cleaning day, and I'm also going to move Mr. Sea cucumber. I have bought some extra carbon to but in the filtration just in case I kill some of the creatures and they put out any toxins..... tomorrow I will do at least a 30% water changed and take some of the non-living things out and give it a good scub. Don't know how I even got the little flat worms. I haven't gotten anything new in that tank for at least 5-6 months??? Thanks for your help attached is another seahorse I have from another tank

Be very carefull about "deep cleanings" because they can cause a lot of trouble, even with the best intent.
What are your nitrate readings?
It is not uncommon for these animals to "bloom" in response to available nutrients, and I would say that just regular maintenance should be enough to limit them in time.

ophi, did water sample today...everything looks good except maybe I could raise the ph a tad bit.... tomorrow I will do a 30% water change and clean the sand good. Thanks for all your help.
