Help Please? Shark Or Fish First?

[p.sandlak]

so i bought a small 2 gallon tank and realized i could not get anything to exciting in it once i started looking into fish, so i went and bought a 20 gallon tank. i used to have a small tank once with a betta and once with goldfish, so i kinda know whats going on but im no expert. i really like the red tailed shark and set up my aquarium for its needs with a couple caves for territories, plants, basically everything the internet and pets stores have told me to do. i also want to add a couple other fish with it (i currently have no fish in my tank), im just not sure if i should put the shark in first wait a week or two before adding other fish, or add a couple other fish that are compatible with the red tailed shark (any suggestions for compatibility) first and then add the shark later. could you please let me know your thoughts, any insight is good on anything

thanks!

the petsmart website says 20 gallons or bigger for the red-tailed shark so i thought it would work? what other cool fish would you recommend

 

[FishAreFriendsNotFood10]

Dwarf/Honey Gourami?
Dwarf South American Apistogramma?
Kribensis?

with a nice school of shoaling fish like tetras? you could also put in a few small corydoras

Pet Store website often underestimate the tank size needed for larger fish, that way you buy more fish. Red tailed sharks grow up to 6 inches and are pretty active and also aggressive to same species and smaller fish. Long story short your tank is just too small.

Agree 20g is too small for a red tail or rainbow shark, they get more aggressive as they get older i find.

I had one in a 20g for a little while (due to some problems) and it just went mad on my other fish, although there was no noticable damage to other fish i know it'd of been stressing them out.

+1 for "fisharefriendsnotfood10" comment too
maybe rams instead of kribs though? i dont know
