Fish Keeping: My Experience with Community Freshwater Tropical Fish

I love animals and have had many pets throughout my lifetime. I've had cats and dogs, mice and rats, hamsters and gerbils, snakes and lizards and even a rabbit. But not until around 8 years ago did I attempt my hand at keeping tropical fish. I always considered fish keeping more of a hobby and thought that fish were really useless as pets because you couldn't pick them up and hold them. I now know differently.

I started out with a 10 gallon tank that came complete with a filter, hood, light, gravel and 2 plastic plants. I bought a Whiptail Catfish and a few Mollies. The Mollies got sick with ich and died. To replace them I bought Guppies who reproduced at an alarming rate. They also got ich and died. After 2 years, and many problems I upgraded to 29 gallon tank and decided to concentrate on fish that were larger and weren't live bearers. The problem with live bearers (Mollies, Guppies and Platies--to name a few) is that they are constantly pregnant and bear live babies. When the babies are born, the larger, adult fish in the tank swoop down and eat them. If you want to keep the babies alive, you need to: A) have a device in the tank (called a breeding trap) to keep them separate from the rest of the population or: B) have another tank that you devote strictly to raising the young. This is a lot of work and soon you have hundreds of fish and a very over crowded tank.

Over the last 6 years I've had a lot of luck with my larger tank and would tell anyone who's thinking about fish keeping to just start with a tank that's at least 25 gallons. Larger tanks hold more water and are less likely to have the temperature variations of smaller tanks (which can kill fish and/or cause fish diseases).

I've tried to maintain a well balanced community tank and had luck with several fish species. Tetras and Barbs are peaceful, colorful fish that do well in community tanks. You need to buy at least 2 because they like to be in groups. Danios are nice community fish. They like to be kept in groups and are fast swimming fish that like to dart around. Plecos are a type of of catfish that will eat all the algae off the glass and keep your tank sparkling clean. They can get big, so don't get one unless you have at least a 25 gallon tank.

I have 2 Kuhli Loaches that were the first fish put into my 29 gallon tank. They look like weird fish-snakes and hide most of the time during the day in caves, but come out at night to eat and swim. I've had an Opaline Gourami and a Gold Gourami. These are peaceful community fish as long as you keep only one or have a different sex pair. I had 2 that were the same sex and were fine until they matured. Then they started fighting---or I should say, the dominant one started biting and attacking the other one. I gave the weaker one to a friend who had a tank because I was afraid it was going to get killed.

Yes, it is a very serious problem, one of many

Caused by the importation of exotics as pets and their subsequent release in south florida.
The "walking catfish" is another. There are actually a whole bunch of problems with freshwater aquatic systems in florida but the "walking catfish" one is the only one that's caught the public's fancy at all (presumably because it is seen on land at times). There are literally dozens of exotic fish species that are problems, along with plants, snails, etc brought in by the tropical fish industry.
As fucked up as florida's terrestrial ecosystems are, they're in great shape compared to her freshwater aquatic ecosystems in at least parts of florida.
