Thanks for your question about your fish, and congratulations on your new family members! I didn't see how recently the tank was set up, but there are a couple of things that could be going on. I would start by checking your water quality - any abnormalities in water quality can make fish have abnormal behaviors, and the water looks a bit murky in the photos you provided. There may be parameters that need to be addressed depending on what you find. If you do not have a water quality kit, they can be purchased at the pet store or an aquarium store, or you can take a sample of your water in for evaluation to these places as well. Some will charge a small fee for this service, just so you are prepared. Also, with recent tank set ups, it can be stressful for fish as they are in a new habitat. I would recommend keeping the light on for only a few hours per day to start, as the bright lights can be shocking for them (since fish don't have eyelids). Gradually you can increase the length of t

Thanks for reaching out, the rule of thumb is 1" of fish per 3 gallons, but smaller tanks are very difficult to keep stable, and saltwater fish are easily stressed by environmental fluctuations (salinity, temperature, dissolved oxygen). Good luck.

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

Salt water aquarium requires a great deal of regular maintenance to keep the fish alive. This can be helped by adding live rock (similar to live coral) to the aquarium. Below is a link to some great information for maintaining a salt water. aquarium.http://www.madhattersreef.com/20-ways-improve-aquarium-husbandry/ I hope that helps and all is well with your fish.

Check the water chemistry. The discoloration could be due to elevated ammonia levels which can cause "burns". Use a home test kit or submit a water sample for testing. The local Petco may do this for free or for a small fee. Aim for an absence (0 ppm) of ammonia and nitrites with nitrates at 20ppm or less. Perform partial water changes to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. The Neons (blue fish) appear to be infected with Ich, a parasite. Treatment is possible with commercial products found in the local Petco. Follow label directions carefully. You will need to treat the entire tank until all traces are gone. Removing a lump from your fish on your own is never recommended. You can cause severe injury. Most broad spectrum antibiotics (Kanaplex, Maracyn, Maracyn 2, etc.) found in the aquarium section of the local Petco should help treat or prevent infection. Choose one and follow label d
