If you are asking about the Black Ghost Knife fish they are natural predators and their prey is any fish small enough for it to catch and kill. They also have the ability to electrocute a fish to stun it. They will kill neons and guppies but mollys may be a bit big for them.
Hardy tropicals such as mollies, platys, swords, guppies, tetras, barbs, danios and rainbows should work fine.
mostly smaller fish like mollies guppies snails and otocinclus
yes, fish guppies,silver sharks and balloon mollies can be together.
There are guppies and mollies.
Mollies,Platies, Guppies, small Tetras (I recommend Black Skirt Tetras), Corydoras, (Electric or German) Blue Ram Cichlid, and last but not least............ Apple Snails. ;)
you could have guppies angel fish neon tetras platties blue rams tiger barbs and and and mollies otto cats cherry barb
Yes. Tetras, guppies and angelfish can coexist in one fish tank. Keep in mind that Angel fish will get territorial when they are mating.
Fish that have long, wavy fins should not be put with guppies, because guppies will nibble their long fins. Also, many bigger fish will eat guppies. Keep a separate tank with guppies and a few "cleaner" fish, which do not harm guppies.
guppies, mollies, scord fish. that's about it
Guppies, mosquitofish, sharks, mollies, and platies.
You will find that there is some disagreement about which fish are the easiest to raise, but Danios and Barbs appear on almost everyones list. On many lists you will find Tetras, Guppies, Mollies, Swordtails and Gouramis.
swordtails
