I have 2 glo fish what kind of tank should I get?
At the very least, a 10 gallon tank with a filter, heater, hood and light. Ideally, the tank should be up and running (without fish) until it cycles properly. This means there needs to be sufficient time for beneficial bacteria to colonize the tank and filter to be able to break down wastes, namely ammonia and nitrites and to a lesser degree, nitrates. This can take several weeks to occur. You can cycle a tank with fish in it, but it will require daily testing of water chemistry to prevent a toxic build up of ammonia and/or nitrites. Either can kill your fish if not treated.

I have three glo fishes in my tank. Two of them appear to be very bloated. Not only is one of them more bloated than the other, but it is also losing some of its color in the lower part of its body and it has a rough look as if its scales were starti
The bloating could be infection. It may also be parasitic infection, constipation or swim bladder disease. You cannot discount them being gravid (pregnant). Glo fish are egg layers, so they could be females readying to spawn (release eggs). First check water chemistry and quality. Clean water is critical to having healthy fish or to having fish recover from illness or injury. Use a home test kit or submit a water sample for testing. Most pet stores will do this for free or for a small fee. An established tank will have 0 ppm ammonia and nitrites with a nitrate level of 20 ppm or less. If your tank shows any level of ammonia or nitrites, perform a partial water change (no more than 30% total volume at a time) using conditioned water. Makebsurebit is temperature matched as well to prevent stress or shock. Glofish do best between 72 F and 80 F. Once water quality is squared away, fast the fish for 2-3 days, then feed tiny bits of cooked and shelled green peas. This will help with consti

I went on vacation and put a vacation feeder in the tank when I came home his tank was a sandy color. After cleaning his tank complete I put him back in and after that he hasn't been the same going on a week with out eating. What did I do wrong? Now
Check the water chemistry. Confirm ammonia and nitrite levels are 0.25ppm or less and nitrates are 40ppm or less. Use a liquid test kit or submit a sample for testing. Most pet stores or aquarists will do this for free or for a small fee. Partial water changes, about 30% can be done to decrease high levels. Use only aged or conditioned water that is temperature matched to prevent further stress or shock. My preferences for water conditioning are AmQuel Plus and NovAqua in addition to StressCoat. Confirm water temperature between 78F and 80F. You can soak pellets in some garlic juice to stimulate his appetite.

I’m getting a 20 gallln tank and I would like to know what are the best tropical freshwater fish that I could get? I would like to get a pleco, but he would get to big for my tank, so I’m wondering if I could donate him to my locomotive petco in The
Thanks for using Boop by Petco! This could be due to pain or discomfort as he could have hurt himself. However, it could also be coincidental. If he is otherwise doing well without limping, I think it would be ok to monitor him for now. However, if he develops a limp or any other signs such as crying in pain, inappetence or continued lethargy, have him evaluated by a veterinarian for further assessment and treatment. They can check him for any evidence of pain and treat him based on findings. Good luck and have a great day!

I have 2 salmenese tiger fish and two smaller fish in approximately 3.5 L bowl. I bought them on 1 April. 3 act normal but one act abnormal from first day. One salmenese tiger fish doesn't move much first it stayed at bottom now it's gapping at surfa
The bowl looks definitively a bit small for the two fishes. To understand exactly what is going on you need to approach this problem radically but logically. Begin by submitting a water sample for quality testing. Most pet stores will do this for free or a nominal fee. Clinical examination should always include a water quality check, even if you have done so already. Water testing should be performed with a quality test kit, measuring NH4, NO2 and NO3. High ammonia levels, PH imbalances may be responsible for these signs. Oxygen concentration and quality of the filters should be determined as well. If water quality is good and there are no major imbalances, your fish should get examined to look for any sign of bacterial/fungal infection and eventually water should be treated. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
