Hi folks! So I have had my 55 gallon set up and running for a several months now. Over the holidays, I got a new pressurized CO2 system and now I'm about to upgrade to a larger tank. I will probably keep the 55 gallon tank running and move it into my office. The new 100 gallon tank is going to be my new display tank. I'll move most of my plants, my lights and my CO2 system over to the new tank, and I will downgrade my 55 gallon to a low tech tank. The only fish of my current stock that I want to move over to the new bigger tank will be my angelfish (Beethoven). Beethoven's body is now about 2.5 - 3 inches in diameter. If you include his fins and tail he is about 5-6 inches total. And while he is growing well and seems to be generally happy, I just feel like the 55 gallon is not enough room for him anymore. Lately, he seems to be having more trouble maneuvering between all the plants and driftwood in the tank. Also, the edges of his fins are beginning to look a little rough and I have noticed that the blackskirts and rummynose tetras have starting chasing him around the tank a bit. I'm not sure if his fins are just snagging or if the tetras are actually nipping at him. But either way, I'm going to move him out. I just love him so much and he has become the favorite of the house, because he is so interactive with us. He is so docile and gentle with all the other fish. He has never once shown any aggression at all toward my other fish. And he just puts up with all the other fish (like my rambunctious cories) with such grace and patience. Of course, there was that time he did eat all of my Bolivian Ram fry... he sucked them right out of the nursery net. LOL! But in general he is gentle, very intelligent, and he is super friendly with me and my family. Most of my other fish couldn't care less about us... but Beethoven seems to generally take an interest in us and whatever we are doing. So... now I have to figure out a new stocking plan for the 100 gallon which I am getting this week. What ever I pick needs to be compatible with at least one angelfish. Because Beethoven is definitely going into the new tank and I don't want to be back in the same boat again in 6 months. I like the idea of Rainbow Fish a lot. I don't have any of those yet so I was kind of thinking of going that route. What do you guys think? Will the rainbows be nippy with Beethoven? Or are they more docile than tetras? What about a Paradise Fish? I like the look of them but will they get along with an Angelfish? What are some other good choices to go with an Angelfish? I currently have Julii Cories in my 55, so I was thinking about maybe going with some pandas this time. Or... maybe even going the loach route... maybe some Kuhli loaches? Since I'm looking to try some new fish out this time, I guess I should list what I already have in my other three tanks: Otos BlackSkirts Columbian Tetras Bolivian Rams Silver Hatchetfish Julii Cories Angelfish Rummynose Tetras Sunset Gourami Albino Cories Nerite Snails So, that is about it. I'm looking for suggestions in stocking my new 100 gallon tank that will be compatible with an Angelfish. Thanks!
