I am very glad to find this forum! I am still learning about taking care of my fish and aquatic plants, and this forum has been really helpful. We live in Alaska, so resources are a bit scarce but there is a really good aquarium store in town. Currently, I have a 72 gallon tank with a ghost knife, royal pleco, some algae eaters, and a couple of South American puffers. We are designing a build for a new tank for the ghost knife (he’s about 5” now). Looking forward to learning from those with more experience than I!
