Is a rose a rose?

[briangg57]

Why are some small with bubbles and they stay small, and others, like mine,BIG with long tentacles? are there different species of roses?

There is only one species of rose bulb tip anemone, Entacmea quadricolor. Fautin and Allen describe large solitary ones and smaller cloning ones in the wild. Whether these are a separate subspecies or, for whatever reason some are clonal and others only sexual in their reproduction is still an unanswered question as far as I know. Perhaps conditions/location is the explanation for the variability.

What beautiful roses! You so need to sell me one of those! PLEASE consider shipping!

As far as your question goes, I was propagating nems (cutting them) awhile back and still have a few of them. These nems are genetically identical, yet one stay short and has bubbles. The other is HUGE, long and stringy like yours are.

IMO the long stringy one is the healthier of the two, but that's not to say bubbles are a bad thing. I really don't know.

They are all the same species at any rate...along the green, brown, whatever color BTA's. They are all Entacmaea quadricolor.

Here's a pic of mine...

i have a similar looking rose that splits often.

Im beginning to think that they lose the bubbles when they get older because ive never seen a big one with bubbles.

Ive got a GBTA thats bubbled all the time unless its hungry, after I feed it goes back to bubbles. The only other time I've seen it long is when I moved it to the new 75, it bubbled up again after about a week.

Mine is smaller though.. probably 7 inches when fully expanded.

Mine had bubbles when it was small. Now it looks exactly like yours with very long tentacles.

As far as I know nobody really knows why BTAs bubble or don't. In my experience, though, the weaker the light source and the hungrier they are, the less likely they are to bubble. Mine also get a lot bigger when they're hungry, almost like they're stretching out for a meal.

im not sure why they bubble or not. alot of people like to think it has to do with light strength but i have mine under the stock PCs of my biocube and it stays bubbly all the time and i have seen people with them under 400w MH and the tentacles will be long and stringy, which i think 400w fixtures are far too intense unless you have an abnormally deep tank.

one of mine has bubbles one does not. i will snap a pic ...

i think it may be age and location(necessity). mine look like that as well.
Here's most recent pic--right after it split the night before:
