I was told that it's because of too much blue in the spectrum, or something
similar... One color makes it grow tall, one color makes it bushy, not
tall.... IIRC, blue makes it go tall, red makes it bushy.... Anachris is the
same way, if the light has more reds, it'll be bushier leaves, thicker
between branches, and more blue will make it reach for the top of the
water....

I could be wrong, and I reserve the right to be wrong at anytime without
hesitation... haha....

my Caboma always sucks, I always sucker in and buy it because it looks so
nice... at first. Is this a true aquarium plant, anyone know? I know many
"aquarium" plants sold are not really meant to be underwater, people just
sell them for the purpose and they often don't do well.

For me, the trick is to never top it. Start with a nice, thick, batch, and
never, ever top it. Instead, discard the bottoms and replant the tops

Of course, I don't always have the discipline to do that. :-)

It's almost certainly that you don't have enough light. Cabomba really
requires a well-lit tank. For a small tank like a 15g, well-lit
probably means something like 80W. (The watts per gallon rules don't
really work for small or large tanks.)

You might do better with a less light-demanding plant such as
Limnophila, although frankly you might not have enough light for that
to do well either.

Cabomba is a hassle. This cannot be stopped.

Low maintenance plants - Crypt (once over first dieback) Hygro and
Ludwiga. All root well and do not get straggley.

This is the limnophila sessiliflora or ambulia?

Actually Red, it's the opposite. The blue spectrum encourages short and
bushy growth while the red spectrum makes plants grow long and leggy.

That hasn't been my experience. My Cabomba actually grows bushier in my
moderate-light tank, probably because it grows slower.

Yes, I was thinking Limnophila sessiliflora, a.k.a. ambulia. Although
Limnophila aquatica might do OK too. Limnophila aromatica would
definitely require more light, however.

Again, I don't know if 30W in a 15g will support L. sessiflora either.
Tbat's pretty low light. But it would be more likely to do well, and
has a similar look to cabomba.

The original poster has 30W on a 15g, which sounds like pretty low
light to me. I don't know what kind of lighting is on your
"moderate-light" tank, but I suspect that it's much better-lit than
that.

Unfortunately, I don't know of any measurement that's both easy and
accurate for describing the light level in a tank. So your
moderate-light might be something that I would call a high-light.
Someone needs to mass-produce cheap underwater light meters to resolve
the problem. :-)

"Watts per gallon" isn't really meaningful when you compare wildly
divergent tank sizes. Yes, 2 wpg is likely more than you need for a
110 gallon. It's less than you need for a 15 gallon (at least to grow
high-light plants). It might be just about right for a 65 gallon.

You'll see a lof of argument about exactly how light needs change with
the size and shape of the aquarium. However, I can tell you
unequivocably that the same wpg number won't provide equivalent
lighting in wildly different aquaria. For example, putting 6 Watts on
a 3 gallon tank may be 2 wpg, but won't grow much.

I'm curious, what variety of cabomba are you growing? I know that, for
example, Cabomba furcáta (a.k.a. Red Cabomba) requires more light than
Cabomba caroliniana (a.k.a. Green Cabomba). In either case, I would
expect the original poster to have trouble with either one given his
lighting.

I have 40w on my 29gal. and my Cabomba grows fine.

Nah. I have 2.4 watts per gallon on a 29 gallon tank. No CO2, and not a speck
of algae. A 29 gallon tank is much higher than a 15g, so I bet he's got more
light than me, from a plant's POV. Especially since my bulb is really old.

However, I do agree that Limnophila is much easier to keep. I particularly
like Limnophila indica. It turns a nice red-yellow under high light, a
striking lime green under moderate light. Fast grower, that stays attractive
and bushy even if you top it.

Oops. Typo. I have 2.2 wpg on a 29 gallon tank.
