Question Echinodorus osiris

I went to a not-so local LFS and found a few pots of "ruby swords" which I suspect to be Melon Swords, E. osiris. I grabbed a pot, thinking it might make a good feature plant in my high light 40B...

Rams and most other cichlids are pigs. I don't usually have trouble with coloring and feeding, but I would not be surprised if they are being brats.

Also, by removing that odd male you have...

Nice! Do you know what you want to do with it aside from the AWC?

Perhaps you could do a thread on it.

I wasn't aware they made a special knife for this application. I'll have to check next time I'm at the hardware store.



Don't forget WD-40! haha

So you don't score 1/4 inch acrylic? I guess that means I wasn't scoring it wrong, just using the wrong method. If I get a jigsaw I can probably get a straight line using the same straightedge I used...

Both guesses are correct. Both cases will require the same amount of effort from the pump because the tubing length is the same.

Height does not have an impact in this situation, so the same...
