This is not based on gallons of water but the foot print of the tank. On average, I would say 2 to 2 1/2 pounds would be sufficent for that size. Most tanks you can use the 1 pound per gallon rule. However planted tanks and some species require a deeper substrate bed.
How much gravel for 200 gallon tank
nooo??? why would it?
The rule of thumb is usually a gallon per fish, so six gallons would be good. If the fish are on the large side (like a goldfish), then a seven gallon tank would be ideal.
gravel
length and width for a 55 gallon fish tank
It doesnt really matter if you want it coloured or plain whatever suits your fish tank! :) x
A betta fish would be much more suited to a 1 gallon tank than a 'variety'. You shouldn't keep much more than one fish per gallon anyway.
no you should not
In oder to really answer that, I'd need more info? What kind of fish? What kind of substrate (gravel)?
Measure the tank. You can get fancy and subtract the thickness of the walls (and the gravel on the bottom).
Danios or glofish would be a good fish to put in the tank. They are schooling fish which means you would need at least three and I wouldn't put more than 5 in a ten gallon tank.
Remove the sick fish..... the fish that has the ich should be put in a hospital tank then treated for ich, corals do not get ich, only the fish, so a ten gallon tank with a aerator would be ideal for a hospital tank....
