Pics and a video of my aquariums

26 Aug

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.

Fast and easy freshwater aquarium

3 Apr

Some of my older Neon Tetras and Harlequin Rasboras have died , so yesterday I bought 4 Neons and 3 Rasboras. I want to quarantine them for a few weeks so I set up a simple 10 gallon tank.

Also, my male Betta was getting beat up by the large Marble Angels that have been spawning in their 29 gallon tank. I need a new peaceful home for the Betta.

I washed some sand that I bought at Menards, a "home center". This is probably $1.50 worth of sand.

Here is the heater and a sponge filter. The sponge filter was in another tank. I washed it out but it has a nice bacterial colony going

I caught the Betta in a net but when I can I prefer to use my hands to transfer the fish.

The water is half "fresh" water and half "used" water from the Bettas tank.

I planted Watercress that I got at the Asian market. A bunch cost $1.10 and I used about a third of it in this tank.

After one day the water is clear and the Neons are looking good.

I hope the Betta gets his blue color back. Those Angels kept him in hiding and he certainly looked unhappy.

I left the water level down an inch or so. I expect the Watercress to reach up and come right out of the water. The tank should have a “jungley” look to it. I’ll take some pictures in a week or so.

The only way this “instant tank” works is because I pulled the sponge filter from another tank.  Don’t set up a brand new tank and throw Neons in there. Start with guppies and wait 6 weeks, then add Neons or whatever you like.

Harlequin Rasboras are not a Rasbora

25 Dec

I bought 5 Harlequin Rasboras many months ago, the price was right and they looked healthy.

For some reason I had the idea that these were a delicate fish, sensitive to temperature and stress. I have been thrilled to find that they eat like pigs, get along in a tank of semi-aggessive Barbs and Gouramis, and don’t seem to be bothered by temps in the low 70’s F.  I do have the tank closer to 74-78 now but when it was a little cooler they didn’t seem to mind.

They stay in their school, generally in the middle to upper third of the tank. They are not shy at feeding time.

I really, really love these fish. I wish I had a 50 gallon display tank with 50 of them. It would be stunning. I’ll have to make a list of my favorite fish someday. The Harlequin Rasbora would be in the Top Ten.

What is a Harlequin anyway? If you Google images for “Harlequin” you will see pictures of a Court-Jester type character wearing bright clothing that features triangular patches.

The crazy thing is that the Harlequin Rasbora is not even a Rasbora. It’s scientific name has always been Rasbora heteromorpha, which means “different-shaped Rasbora” because…Ta Da… it is shaped differently than other Rasboras. After years and years of having this name the Harlequin Rasbora has been placed in the genus Trigonostigma, so the name is now Trigonostigma heteromorpha, which confuses me because it’s not a “different-shaped” Trigonostigma.
By the way, it appears to me that Trigono must be “triangular” and stigma is “mark” so that makes sense.
