fish hardiness

I cant rate all of these fish but from my experience, cories are pretty hardy and I have never had any trouble with them.
If your tank is established and regularly maintained, neons are not hard to take care of either. The biggest problem with neons is when you initially get them, you are bound to lose a few, but the ones that survive the first few weeks should do fine as long as you keep the water clean. For example, out of 15 neons, I lost 3 within the first two weeks, but the other 12 are doing great after about 5 mos.

:read: LiveAquaria has profiles on most, if not all of those fish, and their profiles list difficulty/hardiness. Good luck with your research!

white clouds never owned them, but i've heard they are quite hardy. they get about 1.5 inches long and need to be in a school of 6 or more

guppies also pretty hardy, they breed like rabbits. also get about 1.5" long and should be kept in groups/schools with 1 male for every 2-3 females.

platys never owned them, but they are not too hard to take care of either. these get 2-3 inches long and the same rules apply as to guppies.

Silver/bala sharks these can be more difficult. they are very hyper fish and get up to 12-14 inches long. they need no smaller than a 5 foot long aquarium and should be kept in schools of 6 or more fish. they like a heavily planted tank. they have often been known to "spazz" out and run into the walls of the tank, injuring or killing themselves. this is why they need such a large tank, to allow them plenty of swimming room.

corys these are cute little bottom feeders that range from 1 inch long, to 4 inches, depending on species. they are fairly hardy and should be kept in a school of 6 or more.

danios are almost impossible to kill. these are often used for cycling new tanks. they are also very hyper and should be kept in a 20g tank or larger in a school of 6 or more

glass catfish i really don't know much about these, sorry.

neon tetras these are famously hard to acclimate to a new tank. you should expect to lose about 30% of them when you first introduce them to the tank. once they are in and established though, they are quite hardy and can live for up to 10 years! they are also schooling fish and should be kept in a school of 6 or more.

guaramis are fairly hardy. they range from 2" to 18" long, depending on species (dwarf species are usually 2-3 inches, standard species are 4-6, kissing gouramis are 6-8, and giant gouramis anywhere from 12-18 inches) these fish do not get along well in groups and should be kept either alone, or in small groups in a VERY large tank. pearl gouramis are the exception and do fine in groups. they are the most placid and peaceful of the gourami species.

scissortail rasboras i don't know much about these except that they should be kept in schools of 6 or more and get about 2.5" long.

dab=nios and whitecouds are hardy..I know for a fact that danios work if you want to do a fish cycle..never lost one to the cycle but a couple of them sure did like the inside of my ac filter..LOL
I found out they like swimming against a current...LOL


I know white clouds are tough too..
I wouldn't rate the goouramis as hardy compared to the other two..but I never had trouble raising them.
neons are easy to keep in an established tank..
the others I've never had in tanks.
