Ok I was told that this plant was a Rotala sp. of some type, but after looking at diferent pics I am questioning what it really is. I was going to sell it to someone that wanted some rotala but they said they thought it was a Ludwigia of some type. I didn't think so but i'm far from knowing what i'm doing so please let me know. All I know is that in low light it is green and in stronger lighting is is red. Mine only has red on the crowns.

It's definately a Ludwgia species and not a Rotala. I'll let the experts here decide which one.

On a side note, there is a fair bit of BBA algae on the plants in that tank. That's fine, but just make sure your potential buyers are aware of the issue.

Yes I know, I've been battleing this crap for a while. I use Florish excel on it every day and I reduced the light time on the tank. I haven't had luck with shrimp in the tank to try and eat the algae, they keep disapearing....My clown loaches are my suspect.

Excel is very hard on shrimp, so that is more likely to be the problem. I blamed my Yoyo loaches for the disappearance of my shrimp until I learned that Excel and shrimp are incompatible.

It looks like it's probably Ludwigia repens x arcuata.

I've used moderate amounts of Excel with shrimp (Amanos, cherries) without issue.

Dosing per the bottle directions probably doesn't bother them, but "common knowledge" says to use 2 times or more dosage to fight algae.

I was adding about 12mls per day to my 40 breeder and a similar amount to my 75. In any case, I think that adding Excel should only be regarded as 'the icing on the cake' in much the same way that adding herbivores is, not as a panacea for all algae problems. Megadosing it is both expensive and is indeed risky for some inhabitants. But that's no doubt a topic for another thread.
