I've been considering cories for my new tank.. Everyone always says they need very clean substrate? What does that mean? My hornwort is always losing spines.. Would this hurt cories? :s
All fish need a clean tank, but cories do well with a soft substate, as they like to bury and move along on it. Sand is nice, but a small pebble bottom would work. I had no luck with Hornwort, and it immediately lost all it's "leaves". They will not hurt the fish.
Well I read it's common for hornwort to melt down.
And I am looking into getting a bulb at home depot.. The fish store ones are overpriced and OFL said they are the same thing. I don't really know what to look for for my 17gal though D:
I figured a hornwort would survive until I got it since they are indestructible.
I have had an anubias and java fern with nothing but a small LED light for months, and they (even the java fern) have grown a lot :D My java fern has the little "seed" things on it, but none have sprouted.
I got another "hard to kill" plant, wisteria, that melted down over two months and there is nothing left. I read that people grew them in "dark rooms" and they were fine.. so I don't know what I did there.
My hornwort is doing okayish.. I have 3 bunches.. one is great, one is okay, one is not so swell. I also planted a little sprig and it seems to be growing. The not so swell one still has a green stem so I have hope :p
