schooling

So I have a oscar that's around 4-5 inches, I wanna add some tank mates but I've tried in the past but he just ate them. I would like to have a schooling fish maybe like a black skirt tetra or something big enough to fend for their own. Thanks

Yesterday, I came to the decision to swap my tank from cold water to tropical. I sold my WCMM and Corydoras, and now have an 18 Gallon tank empty and ready for a fresh start. I done a 95% water change and did not wash the substrate so as not to have to cycle again, though I suspect I may go...

Hi guys! I'm new to this site. I have a 20gal (high) tank with pool filter sand and mopani wood. My current plan: - 2x m/f Dwarf Gourami (orange coloring) - 8x pygmy corycats - cherry or amano shrimp colony What school would complement the Dwarf Gourami and light substrate the best? (options...

I lost one of my three peppered corycats today. Since my once tiny school is now a pair, should I replace the lost cory? If so, will a new peppered cory school well with the other two (who I’ve had for about a year)? I also have 3 oto cats, 5 harlequin rasboras, and a honey Gourami in the tank...

Hi! I recently acquired a new tank on Craigslist... it is a five gallon with two Mollies and one Black Skirt Tetra. I bought the tank for my shrimps, wasn't told it already contained fish. I know that the black skirt is a schooling fish so I was planning on moving him/her to my 10 gallon when...

I'm new to fishkeeping and yesterday I visited the LFS and purchased my first fish: 6 Zebra Danios. I carefully added them to the tank, making sure not to pour any of the LFS water into my tank. So far they appear to be doing well, although I haven't fed them yet. I've noticed, however, that...

Hi! My name is Briana, i'm new here, but i've been keeping fish about 10 years now. Anyhow, i have a question about my lemon tetras, i got 4 of them a few years ago, and over the time 2 of them have died. The remaining two seem pretty sad, so i went to the local fish stores and neither of them...
