Thanks for reaching out. Testing water quality for pH, ammonia, nitrite and nitrate is the first step, correct any problems. There are few diseases transmitted between fish and invertebrates. If problems persist, a visit to a veterinarian is recommended. Good luck.

I have an issue, this involves all my fish I am moving from Georgia to Utah, and of course that’s a long distance by car, but if will also restrain me from seeing my fish due to the fact that I will be flying there. How do I feed them while they’re b
Thanks for reaching out. If is a good idea to fast for 1-2 days prior to shipment, this decreased feces and will help to keep the ammonia down. Typically clear bags are utilized with about 50% water, and 50% air/oxygen used. A local pet store might be able to assist, as they get shipment in (so have older bags and boxes, which need to be disinfected) and hopefully the skills to ship. Check with the airline also, box needs to be well labelled "LIE ANIMALS" and "THIS END UP". Sometimes a health certificate for interstate travel is needed, so contact airline and State of Utah, veterinarian. Good luck.

I have a 65 litre aquarium tank with 8 small tiger barbs fish ,6 Red eye tetra fish, 2 big golden molly, 2 rainbow sharks.........so can I add Discus Fish with these tank mates ? If yes ...if no ....so which tank mates is suitable for discus fish ? I
Thanks for your questions about your tank. You have a number of fish in your tank already - a general rule of thumb is 2.5 square centimeters of fish per 3.8 liters. Depending on how large your fish are, you may be close to the carrying capacity of your tank, and you will also need to plan on how the fish in your tank will grow over time (mostly the rainbow sharks). If you are looking for tank mates for discus, it is best to look for fish that are housed in the same temperature zone, and occupy different areas in the water column than they do. Examples would be bottom feeders like cory catfish, those that live on the sides and bottom such as plecos, and those that are in the middle of the water column like some species of tetras. For the question about vacation - I would not recommend leaving your tank for that long without someone checking on it regularly. Power outages can be detrimental for tanks, and water changes or additions would likely be required. Also, automatic feeders als

I'm doing a project for school about fish and here are some questions I have: What kind of fish is easiest to take care of? What size tank should someone start out with? What are some things people don't know about fish? What are the most common reas
Guppies or Neons are excellent "starter" fish. Care is simple and they are inexpensive. A standard 10 gallon tank is recommended to start. Most people don' t realize the amount of "work" needed to maintain a tank. Filter maintenance, monitoring water chemistry, water changes, monitoring fish health and providing a balanced diet are just a few items that need regular attention to keep a tank thriving. Even though fish aren't as cuddly as cats and dogs, they do have their own personalities and even respond to their owners, especially at feeding time! Studies have shown that simply watching fish in a tank can lead to a reduction in both heart rate and blood pressure. It is quite relaxing.
