Definitely! The tetras aren't as subdued though..
I finally see the image you put up Pitluvs, they do look pretty! Like glowlights :D They must colour up when you bring them home, like bettas..
Yes, just like Glowlite (I have a few of those too)! Only Glowlights is like a red, these guys have an orange glow. They're my favorite, besides my Swords. They just sit around the tank like "Yup, another Thursday afternoon... wonder what's on the menu today?" while my Tetras are like "asdfhsdhytr OMGGG FISH kdhafsyr HUNGRY *SPAZ*"
I have more of a MPAD thing... Multiple Pet Acquistion Disorder.. Anything cute or in distress will do XD But I've improved now..
Tetras are fun to watch, even danios.. They look like they're from Speed the movie.. "OMG If we stop moving we'll dieee!!!1!!1"
What about cories and otos? Do they absolutely need sand? Or is medium gravel ok? No pointies...
Otos don't even need gravel or sand, they tend to suck on the tank walls and the leaves of plants. Fine gravel is best for cories, with medium you may find a lot of their food sinking down in between where even they can't find it.
