Thank you AdamTill and pleconut for your help

Good idea on the spotlight. Now just to get one ... lol. I have not seen any damage on the Amazon swords, but they are welcome to munch on em if they want.

Ahh just looked it up: for others who did not know, courgettes are zuccini

Thanks pleconut. I have started an algae tank but as cold as everything is around here lately, even in partial sunlight, I cannot get anything growing green yet. Its been about 3 or 4 weeks but all I am getting is white fuzz on my rocks in the algae growing tank. I will have to look up courgettes ...

I did a search and looked at all the Otos that had pictures under the Cat-eLog but although a few were close, none matched my Otos I purchased from my LFS. Can anyone ID these? There are 2 different Otos in my tank - 3 are the all dark with white under belly and 1 the lighter guy. Thanks in advance ...
