i have a 29g tall tank. currently i have 2 otos, 6 redeye tetra, and just bought 2 baby angel fish (the size of redeye tetra). im wondering how many full grown "adult" angel fish i can fit in that tank? i will take out the redeye tetra if needed. also might add 2-3 cory. they r assorted angelfish from my LFS.
