I have a 55 gallon planted community which I love. All is peaceful, however there is one thing missing. I have pretty much no life at the top of the aquarium. All of my fish besides my solitary, juvenile angelfish are in the middle section. In my tank I have: 1 x Angelfish 11 x Bleeding heart tetras 8 x Three lined cories 10 x Kuhli Loaches 6 x Zebra Loaches 2 x Bolivian Rams 2 x Bristlenose plecos 4 x Ottos It may seem pretty stocked, but the tank is planted, has ample room on the bottom for all the bottom feeders to co-exist nicely and I still have soooo much room in the top of the tank. I have no problem with filtration. I have more than enough. I have an external filter rated for 600L and then I have a fluval U4 internal, so ample filtration. I do 30-40% PWCs each week. I would really like to get some more angels. I would like at least one more. I would love more than 2, however is a trio bad? Will 2 pair up and gang up on one? I guess I couldn't stretch to 4 angels? What would be the maximum number with the stock I have? I love watching lots of angels, and I feel kinda sorry for my loner angel! Thanks Abbey!
