My last animal in the 40 gallon tank (a zebra danio) except for Plecy died on 1/4/06. I treated thetank for 9 days with Maracyn I (erythromycin) and Maracyn II (minocycline) by Mardel to try tokill any leftover fish tuberculosis. Plecy seems immune but may carry it. The antibiotics at leastshould have killed bacteria in the water. After that, I did my weekly 50% water change and thentreated the tank with MelaFix and PimaFix by Aquarium Pharmaceuticals for 6 days. During thistime, Plecy developed something strange that I have never seen on any fish. He got a few smallspots on his back and on one pectoral fin where it appeared his color was simply gone. I haveseen bacterial and fungal infections and color changes before many times. This was somethingnew. I do not have a clue. It was not washing out either. He was fully dark but for those spotswhere you could see a few dots of the color with the rest vanished. I tested the ammonia in casethe antibiotics had killed the good bacteria (those kinds had not before) on 1/18/06, and the testshowed no ammonia.

An overview of our 40 gallon aquarium. It started as a top Fin 20 gallon kit but I then bought a bigger tank due to advice from a professional. Added a Fluval 50 power filter and top Fin 200 watt.Waiting to cycle it when my master test kit comes in the mail. Put a lot of thought and time in setting this 40 gallon up but it's a work in process. Please follow my videos and my journey on making my aquarium a healthy and thriving community for fishs.So, lets start with tank size and and kinds of tropical fish. Most tropical fish will get to be as large as one to three inches in length. A good rule of thumb for tropical community fish is 1" of fish per gallon of water. If you plan on having more than 10 fish (depending on their adult size), you may want to invest in a larger aquarium such as a 20 or 40 gallon. You will also need to purchase a hood with a UV light. Most aquariums that are sold in the stores include this. For tropical fish, always make sure to purchase a thermometer. These may be purchased at your local pet store. They have adhesive on them and may be placed on the outside of the aquarium. Along with this, you will need to purchase an aquarium heater(most heaters are easy to use and have valves for controlling your water temperature) and a filter. The filters come in all kinds and sizes. I use a filter that fits over the outside of the aquarium, and these filters work very well! They are power filters and have filter cartridges that must be replaced approximately every two weeks. Under- gravel filters are preferred by some individuals, but power filters are the most popular. They are easy to maintain and work extremely well at keeping your aquarium water filtered. See photo under the article section, Cleaning Your Aquarium.To get started you just need to add filtration, gravel, pump, heater and thermostat (if you would like a marine setup), cleaning tools, dechlorination and a chemical test kit. Being a glass setup it is unlikely to scratch and can marks can be polished out as needs be. So if you are looking for a medium sized glass 40 gallon aquarium on a budget with room to progress your fish keeping skills that tank is truly a Grreat Choice! .There are many methods for filtering a 40 gallon aquarium adequately. Some recommended filters are: AquaClear 500, Filstar XP2, Fluval 204, Emperor 400, Eheim Ecco 2233, or H.O.T. Magnum 250. All of these methods would benefit from an airstone.
