I've got some old(and nearly dead. . .) rhysomes of java fern that I was thinking about gluing to the back of my 20 gallon(divided with bettas) tank. Would they be able to grow like that or would I need to line the back of the tank with something first?
If you can use super glue gel in a reef tank, I've only got to assume that it is safe to use with plants and freshwater fish. I don't have anything super delicate with them anyway. Just the bettas. More curious if the plant could attach itself to the glass, or if I need to put a craft mesh background on there so it will be able to attach and spread.
I have used Superglue gel (doesn't run") to attach plants to rocks and wood. First I dry the surface with a paper towel, one drop of gell, place plant and hold for 20 seconds, put in water. The gel does dry into a white crystal-like substance, so one drop is less noticeable until the plant grows and covers it up.
