I just upgraded to a 20 gallon aquarium. Will these fish get along?

Question

Ok, I just upgraded my 10 gallon, to a 20 gallon aquarium. I have 4 Neon Tetras and 1 betta. I went to Petsmart today to see what i liked. I came up with these:

-Gold Skirt Tetra
-Tiger Barb
-Red Glass Barb
-Red Tailed Shark
-Australian Rainbow
-Long Finned Red Minor Tetra
-Rosey Barb
-Albino Rainbow Shark

Which of those would get along with my current fish? Also, of those that can get along, how many can I safely put in?

Answer 1

Get 7 Rosey Barbs and 5 more Neon Tetras. This will give you a better looking tank and happier fish. Also, you might like 3 Cory Cats.

Gold Skirt Tetra- dyed fish (inhumane); tend to be nippy
Tiger Barb- very nippy; will tear your Betta apart
Red Glass Barb-
Red Tailed Shark- fairly aggressive; will chase your Betta
Australian Rainbowfish- very active; may stress the Betta
Long Finned Red Minor Tetra-
Rosey Barb- peaceful, colorful, and does well in groups
Albino Rainbow Shark- same as the Redtailed Shark

Answer 2

Only the long finned red minor tetras would be compatible in the strictest sense, being the only community fish in the list. If you plant the tank heavily, (plastic plants will do), you may get away with some gold skirt tetras as well. But the other fish are quite vigorous and though they go well together they will beat the fins off your smaller, calmer fish. The suggestion I go by is "no more than one inch of fish per gallon of water for tropicals". This would mean you are at the saturation point with 4 neon, 1 betta, 3 gold skirt and 3 LFRed Minors. That also gives no extra room for an algae eating fish. Remember, every tank is an individual.

Answer 3

The tiger barbs will rip your betta's fins to shreds so skip those. Red glass barb is I believe a color variant of tiger barb so avoid those as well. The red-tailed sharks are territorial and aggresive against other bottom dwellers so get only one. Also depending on size they may harass/try to eat the neons. The australian rainbows would work however they need lots of swimming space so a 20 gallon is really pushing it in terms of space. I would say a couple of small schools of 5-6 gold skirt and red minor tetras might be the best choice. Add them about two weeks apart though to allow your nitrifying bacteria to adjust. Instead of the rainbow sharks I would go with more mellow bottom feeders, such as the various corydoras cats available from petsmart.

Answer 4

Tetra's will be fine,
Tiger barbs are very boisterous and would require a minimum of 6 in a shoal to help stave off any fin nipping of other fish.
RTB's are terrotorial and should not be kept with another shark or fish of similar shape (flying foxes etc)
Ozzie Rainbows can get fairly large so not really suitable for a 20gallon.
Rosey barbs are a nice addition however they like cooler temps than the tetra's, but could cope with 80f

I would perhaps suggest increasing the amount of tetra's introducing some cory's for the bottom and then maybe looking at something like halfbeaks, hatchets or even guppys for the top.

Answer 5

Tiger Barbs, Sharks, and Rainbows all are too large and/or too active for a 20 gallon tank. Especially all together!

I've known a couple people to try mixing rosy barbs with bettas and there was nipping and aggression problems both times. You might be luckier, but I wouldn't recommend it if you value your betta's wellbeing.

The gold skirts might be alright, but the betta might nip their large fins.

I'm sorry. Can I recommend that you up your number of neons to 8 or 12 and get some cories or kuhli loaches for the bottom of your tank? especially if you have a sand substrate, since both of those species like a sandy bottom.

Answer 6

You might have to do a little more research or ask at the pet store you have to one or the other either an agressive fish tank that has things like sharks, tiger barb, betta, oscars, angel fish, etc... they will all be ok and teritorial or you can do a comunial fish tank that has things like tetras gold fish, mollys, things that can live together peacefully. If you mix agressive and other fish togher you will with a week or two only have the most agresive fish left becasue he has killed the rest. Trust me after you make this mistake you will see how it adds up Money wise$$$ so its best to make sure they can be in the same tank . Or they will keep getting killed and that same one who survied last time will be the only alive agin!! Good Luck!
I have an agresive Tank it contains
2 oscars
1 paradise fish ( is like a betta)
1 red tailed shark
blue lobster
Plocostomus
2 apple snails
Baby turtle
they are still alive, healthy and dont bother each other.

Answer 7

id stay away from the sharks and barbs. best to keep the tank with related species.
up the neons to 7 and get a school (7) of red minors. some cories would be nice for the bottom, too.

Answer 8

First, tiger barbs might be goof but they are a threat to your bettas. All of the other fish could get along together except for the sharks [one of each species only] With the rest, all of them are schooling fish 6 of them. You decide but be aware of OVERCROWDING your tank.

Answer 9

Barbs are aggressive and will definately eat tetras, The only hope is is you put them all in at once they will get along, but if the barbs establish dominance they will eat all of your tetras.

Answer 10

tiger garbs are nippers and will chase other fish! All tetras and barbs are school fish and should be kept together in groups......A 20 gallon will limit the number of fish you can have ........
