Macros for a 20 FOWLR DT
- Thread starter Twinkies
- Start date
I have some red gracilaria in my 29 gallon FOWLR (trying to cure a hair algae problem). So to stop it from going sexual, how small do I have to keep the clumps? They range from 5 - 10 inches right now...
BTW Twinkies, I also have some Halimeda and Maidens Hair growing in my tank (not introduced by me, just shoots from some LR).

JotaDe,
Gracilaria is a (true) red algae. When it reproduces sexually it forms special male or female parts (I believe all gracilaria are dioecious, which means either male or female, not both). Gracilaria doesn't not break down its cells like caulerpa (although caulerpa is one giant coenocyte cell whereas gracillaria is many cells linked to each other both vertically and horizontally). Also, I don't believe Gracilaria are toxic at all so even if an individual dies it won't release harmful toxins into your tank.
Here's an informative page on red algae which has stuff on their reproduction:

Here is an article from the Journal of Marine Biology on the reproductive ecology of one species of Gracilaria:

Sorry that second link didn't work. I am gonna edit my post. It should work now... at any rate it was a reporductive study done about one species of gracilaria which prob isn't what you have but if you are REALLY interested in its reproduction that might be something to check out
