Aquarium Advice Newbie
We have a 20 gallon freshwater aquarium, currently with a rainbow shark, blue gourami, and two glo-fish (a yellow and red). This has been our most stable population, so far. We've introduced a few other glo-fish that haven't made it. Not sure why. The two we have now are survivors from two different "batches." They stay at the top and are extremely active and too much for the other two fish to keep up with, I think. I think that's why they've lived so well, so far. They occupy a place in the tank the other two big ones don't always hang out and are just too swift to corner or grab. The gourami is the undisputed boss of the tank. He's harassed any other fish we've since introduced, regardless of size or type. We had a couple tiny neon type fish that basically became a three-day snack item. We then also had some scissortail fish that did well for a time, starting with five and eventually going down to three and then two. Now not sure if they are hiding or eaten. Eventually the gourami left them alone, but I think they may have wandered into the shark's domain and got pounced. The shark always seems so mellow and content, munching around the bottom and side and in various decorations. I've seen him dash after some fish, except the gourami, of course, but otherwise just ignores everything. Amazingly, I've managed to scare out one of the tiny neon fish that I have no idea where the little dude is hiding. He's small enough to be anywhere and he's shown up at times I was certain it's been too long since he's been around to still be alive. Yet there he shows up! Anyway, that's our tank, I guess I'm just wondering if we should leave our community as it is, or add any more. I think we could use another algae eater or clean-up fish, but worried he'll conflict with the shark. Apparently, we picked two of the larger and more aggressively territorial types to occupy their respective tank-space. Also, the gourami seems only to get all up on any NEW fish that are brought in. It could care less about the fish already there. I guess they are part of his "territory" now and anything new is just asking to be picked on for a while, right?
