Let’s start with this 30 gallon tank filled with very active fish. Zebra Danios, Odessa Barbs, Tiger Barbs, an Opaline Gourami, Harlequin Rasboras and 3 Kuhli Loaches hiding under the rocks.
Here’s a little 10-gallon tank with young Red Swordtails and a Betta. Since I took this picture I have added 3 Marigold Variatus Platies and some more plants.
Here’s another 10-gallon tank with Silver Mollies and Endler’s Livebearers. Lots of baby fish are starting to show up.
I moved my 3 Pictus catfish into this 29-gallon tank with 3 green Swordtails and my Firemouth Cichlids. In real life this tank looks very nice and I get to see the Pictus Cats a lot more than I did in their previous tank.
When I found the 6-inch Bullhead in the turtle pond I had intended to release him in a nearby creek but instead I put him in the tank with the “bad boys”, the African Cichlid and big Red-tail Shark. The Bullhead just goes about his business, big mouth gulping and gaping as he cruises along. The Cichlid and Shark ignore him. Now the Bullhead has found a place to sleep during the day and I don’t expect to see him too often. This tank is crowded with rocks, wood, and plants (Java Moss).
The Bullhead is in here but he’s hiding.
Here’s the 55-gallon community tank with mostly large Tetras, Angelfish, and Corydoras.
