I would love to get some marimo balls for my 10 gallon Betta tank. I see they can be pretty pricey. Why is that? I've seen them at petsmart for $7, but after closer inspection I see they have some MTS hitch hikers on them. Is there somewhere else I can get them around that price, either on here or somewhere else? I'll most likely drain the tank and take out the crappy Petco gravel and replace it with a plant friendly substrate. I would love some sort of tall plants also, since the light on it fits the tank I was wondering if that was possible?? If anyone has any info let me know! Again, thanks guys. You're all awesome with all the help you offer
