What Size Tank Will I Need When My Fish Are Fully Grown?

[branjie]

Hi, Could someone have a look the list of fish in my community tank at the bottom of this post, and give me an idea of what size tank I will need when my fish are fully grown? My biggest concern is the Black Ghost Knife fish which could get to 50 centimetres. I'm thinking of getting a custom built tank in a few months. Thanks!

the ghost knife is going to need a 6 footer to itself.

a 50G should be big enough for the rest.

I'd say 50 gallon is good, i agree with J4MES, i would actually return the ghost knife because i wouldn't want a 5 foot fish..but that's totally up to you, maybe get a..hmm 1000gallon tank? lolActually, just buy a kiddie swimming pool for the ghost kinfe! I don't really know anyone with fish over a foot long, so i'm not really sure what to do with that ghost knife of yours.

depending on which pleco you have, the tank may turn out to be too small for it eventually.

loads of people have fish over a foot long lol - I'd say a 4 by 2 should be good for the knife

Hm, I'm getting quite attached to my ghost, I don't want to give him up. Having said that, I don't want a 6 foot tank in my house. My LFS has a pleco that's so big it needs a 6 foot tank. I really like my 100 litre octagon tank, but I'll probably get a 50 gallon (190litre) tank when they grow a bit. Thanks for the help.

The Black Ghost Knifefish is going to grow bigger than the rest, the clown loaches can grow to a decent size I believe and the red tail sharks can also grow to a decent size, the rest are quite small fish. 25-30 cm kept in an aquarium for a black ghost. Minimum tank size is 100x45x38cm apparently so much larger for the rest too!

good luck
