Is .5 ammonia bad for the water in your fish tank?
Any ammonia is BAD. Your filter is not working well enough. To keep thing safe you will need to be doing some extra water changes (maybe daily) until the filter is working efficiently.
Ammonia should be kept at 0ppm at all time. It is toxic and leave permanent damage to the fish even if the fish survive it. Either your tank has not been cycled properly or the nitrogen cycle has crashed, or you have not cycled your tank at all. You need increase the partial water change to minimize the damage.
A blobfish uses its fins to paddle and its tail to steer/change direction.
However...
Because the blobfish is a sea-bed fish which lives along the bottom of the sea beds where the pressure is so high, it is impossible for the gas bladder, found in most fish, to achieve perfect buoyancy. Therefore the blobfish evolved gelatine-like flesh which helps them to float in the extremely high pressures without using all of their energy.
A disadvantage of this is that the blobfish has relatively little muscles to help the fins and tails work properly. Therefore when blobfish hunt for food, they merely swallow edible things that simply float in front of it, rather than swimming around hunting food like most fish.
Blobfish are on the verge of extinction because of deep-sea trawler fishing.
Where can you find sunfish in a lake?

Dolphins are marine mammals. They are warm blooded, breathe air with lungs, give birth to live young, and have smooth skin.
Fish are cold blooded, "breathe" water using gills, lay eggs, and have scales.
What causes air bubbles to form on the leaves in a fish bowl left under direct sunlight?
The water in the fishbowl is evapourated which forms air bubbles under the leaves in the fish tank because the evapourated water escapes the bowl of water by travelling as a bubble. The leaves in the fish tank traps the bubble under it causing it to stay there.
