the cause might be a sick fish, a dirty tank, or over feeding.
When u tap into the fish tank, you cause tiny waves to form that scare the fish.
I use a fish tank. But you can get special tanks for them like critter keepers but they don't really hold humidity in very well so I wouldn't recommend it. I do recommend using a fish tank that works very well. But if you use a fish tank you need a special top for it. 10 gallon at tank for the smallest. 10-? will work.
Cause its dead
If a fish tank is filled completely, then anything added to the tank will cause it to overflow, and any disturbance, which might result from the vibrations of a passing truck, will cause it to overflow; in addition, there is an increased risk that some foolish fish might leap out of the tank.
The fish tank would have a volume of 2 feet3.
It is said 1 inch of fish per square inch of SURFACE area of the tank. More than this can overload the bio load of your tank and cause a reset in its cycle.
No hermit crabs need high humidity (70-85%)
yes it would cause the fish to get a disese called ick a fish gets that sickness when they get scared or nervous
This depends on many things like how many fish are in the tank, what is the dying fish diagnosed with and what type of fish are in the tank. If you did want to be on the safe side of your other fish i would remove the fish but unfortunately this could cause less chance of survival because moving the fish can cause stress which will sicken the fish even more so the best solution is to, remove the healthy fish(s) into adifferent area and keep the un healthy fish in the aquarium or fish tank.
Cause there is algae that grows on the side of the tank, and that's what the starfish eat.
Make sure that the filter bag that is in your filter is clean. The cause can also b too many fish or over feeding.
