  1. Dwarf Gourami - Swimming Frantically Along Glass?

    Anabantids
    Hi Everyone, I introduced 2 dwarf gourami to my tank a couple of days ago, a male and a female. They seem quite happy and feed well, I give them a mixed diet of flakes, blood worm and brine shrimp which they love. They're in with 6 cherry barbs - they all seem to tolerate each other, I've...
  2. Clown Loaches changing behavior

    Freshwater and Tropical Fish
    The two clown loaches in my office aquarium have changed their behavior since the introduction of two new fish to the tank. It has been about 10 days since the introduction of two new tetras to the tank. We added the tetras because there was only one tetra before and we deemed that it needed...
  3. Neurotic guppies

    Beginner Freshwater Aquarium
    Howdy I'm a returning aquariumist, so I feel like a noob again. I have a 5 gal tank w/ 6 guppies. While they seem very active, feeding well, interested in their surroundings, a couple appear neurotic. They swim up and down along the leading vertical edge of the tank in several laps until they...

    Livebearers
    Hi everyone! My name is Tanja and I am a Ph.D Student at Florida International University. I am studying the genetics underlying why color and aggression are linked in livebearing fish, using eastern mosquitofish (Gambusia holbrooki). Melanin expression and aggression appears strongly linked...
  5. Guppies "hand rubbing" behavior

    Livebearers
    Hello, I've been running a small aquaponics setup for a few weeks now, using guppies and ghost shrimp.

  7. Do fry have a daddy complex?

    Livebearers
    I noticed a little while ago that my mystery platy fry seem to be schooling with the Betta. He's tolerating their presence well enough. At first I thought it was neat when I saw they were unafraid of him, but today I've been watching and they follow him around like little puppies. He even let...
  8. pictus acting strange

    Catfish
    I recently got a young pictus catfish (about 2 inches) that I was keeping in a 2gallon freshwater aquarium. Normal catfish behavior, spaztic, all over the place, good eater, etc. I've moved him to a larger 20 gallon tank with a few neighbors, an angelfish, a few guppies, tetras, and he was...

    I recently bought a new ryukin goldfish for my aquarium to keep the current one company. However, when I released it the other goldfish that I had already had started bugging it by chasing it and bumping its behind. I'm not quite sure what that means, but from what I've researched by looking...

    Hi everyone, I hope you can help! My girlfriend has had a fishbowl for a couple months now and she had one problem, and now another. She started with a 3 gallon bowl and two fish, a goldfish and a beta. After a little while the beta started chasing the goldfish, but it never really hurt it. We...
