Is an LED flashlight safe for fish if my tank light is broken?

When used as instructed, plant nutrients and fertilizers designed specifically for aquarium plants will not harm aquarium fish. Allow new aquarium plants to settle and establish themselves before adding any fertilizers. Use aquarium plant substrates such as CaribSea Eco-Complete Plant Substrate http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=9087 to get your plants established faster. Seachem Flourish Advance Natural Phytohormone Supplement http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=33890 will help stimulate root growth vital for overall plants health. Even though you have plants with low to moderate light requirements, be sure to use aquarium light specifically designed for planted aquarium use (sometimes called plant lights) and have the lights on between 10 and 12 hours a day. You may need to adjust the photoperiod (the amount of time the light is on) depending on how your plants are doing and to prevent unwanted nuisance algae growth.

You can float it in some warm tap water but it will need to come out of the bag before oxygen levels drop and waste levels rise. Hot water bottles or a light over the tank may also keep temps out of dangerous ranges until you replace the heater. Buy two and keep a spare ready just in case.

Thanks for using Petco Pet Education Center, formerly Petcoach! Tap water should be fine to be honest. It would not hurt to use bottled water but it is not necessary unless you are concerned about the quality of the tap water where you live. Have a good night!

Thanks for reaching out about your fish. Things depend on the difference between the existing water and the future tank. The wider the range, the more stress. Match temperature also, as that provides the most stress. Good luck.

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. I'm sorry to hear that Taino has seizures; these can be scary for both him and whoever sees them. The lighting is not a cause of seizures in dogs. Seizures can be caused by things within the head itself (tumor, stroke, infection or inflammation), or from other systemic causes such as liver disease, kidney disease, certain toxins, etc. When all of these possible causes have been ruled out by diagnostics (bloodwork, MRI, cerebrospinal fluid analysis), it may be determined that a dog has idiopathic epilepsy. I recommend keeping a log of Taino's seizures to note when exactly they happen, how long they last, what they look like, etc. Definitely keep your veterinarian updated whenever he has a seizure, because he may soon require treatment with anti-seizure medication if they become more frequent or severe. I hope this is helpful - best of luck with Taino!

It should be okay to use these tanks as long as they have proper filtration, lighting...etc. Round bowls typically don't have filtration, lighting...etc and that's what will adversely affect the water quality. I hope this helps.

Thanks for reaching out about your aquarium. Sorry not very good at botany but there should be tropical fish clubs that might help in identification. But comments about your tank. First, not sure if light penetration will be good for a plant that low in the water column. Secondly, the balanced rock formation looks tenuous, and might fall. Good luck.
