What fish are compatible with clownfish in a 36 gallon reef tank?
I would suggest either a Neon Goby, Yellowline Goby or Sharknose Goby (Elactinus spp.), Court Jester Goby (Koumansetta rainfordi) also make wonderful additions, A Small Basslet of the genus Liopropoma spp. or a Royal Gramma also should work well with your existing tankmates, and lastly another great group of fishes include Shrimp Goby of the genus Stonogobiops or Amblyeleotris. For shrimp goby, one bonded pair with their commensal snapping shrimp of the genus Alpheus makes a fascinating addition to smaller marine reef aquaria.

What are easy, small pets for beginners? Is a cowfish a good choice?
The Cowfish, or Longhorned Boxfish, is a marine species that should be kept only by experienced aquarists. When stressed, they can release toxins into the water which may harm tank mates. Pacman frogs, leopard geckos, corn snakes or bearded dragons are all easy to keep.

Why is my blood parrot fish lying flat, pale, and can't breathe?
Thanks for reaching out. Pale gills are a serious concern. Providing additional oxygen is necessary for anemic animals to continue to deliver oxygen to organ. An airstone and pump will help, but an oxygen bottle would be better. As for a cause, a gill biopsy would be the first stop to rule in/out parasites or bacterial gill disease. Test and correct water quality. Good luck.

Is my orange fish a goldfish or molly, and what's this egg-like thing?
Mollies do come in gold or orange colorations, but it is difficult to determine from that angle. If you can repost a broadside picture in a new question, that may make identification easier. If it is an egg laying species of fish, the third image could be an egg but I have reservations saying definitively without something for scale. It looks too large to be an egg. As an aside, if you leave the Molly fry in with adults, they will likely be eaten. You can separate the out, remove the adults, use a breeder screen or provide plenty of cover for them.

My new Glofish are hiding and staying at the bottom. Is this normal?
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 time that the lights are on so that you reach a cycle of 10-12 hours of light and 12-14 hours of darkness for them. I hope this gives you a place to start, and I wish you and your mom the best with the new pets!
