Now I need to preface that I know how to stock a tank but I am SO indecisive that I really am not sure what I want to do with my tanks so I need some helping me sort out my ideas into what would work best! I have a 10 gallon and 2 5.5 gallons at the moment which house my community nano fish. Over the summer (which I can't be happy enough starts next week!!) I want to upgrade to a 20 gallon L but after the hassle of moving my 3 tanks because of needing to cut open a wall due to a pipe leakage, I don't know if I can handle the stress of moving them fish again haha. Here is what I have now in my community tanks... (not all in one mind you, just in total - and this doesn't include my other bettas who live alone) 1 female betta 3 Harlequin Rasboras (they were the last 3 in my city and it's been 3 months and no store has stoked any since) 3 male endlers 1 female endler So that's it, just 7 fish. I have some fry, but they don't need to be worried about yet as I will probably give them to a family member. Now I wanted to get either... Ember Tetras A red flame dwarf gourami (one issue would be if I did do a 20, it would house the female betta and this wouldn't work) Or some type of nano rainbow fish But I am thinking of doing either one nano tank with red fish OR koi patterned fish. If I go for Koi I would get a female koi betta, as themale are too expensive! Any suggestions on how you all would house these fish or stock the tanks? I've always had larger tanks so those were easy to stock, but these are small so it's not the same! TIA!
