I&#039;ve had various small community fish living in my heavily planted tank the last couple of years. While it&#039;s &#039;pretty&#039; I feel there&#039;s no character to any of the fish and I&#039;m looking for something bigger.<br />I used to kep a couple of oscars and enjoyed them but I&#039;ve moved on.<br />My water is ph6.4, so soft water lovers are a must. The tank has Duponit fertiliser with a sand substrate and undergravel heated cable; taking the depth to around 3&quot;.<br />How big can I go with a 6&#039;x2&#039;x2&#039; tank?<br />I saw a red tail catfish in the lfs today and fell in love with it.<br />But you&#039;re all going to tell me I&#039;ll need a bigger tank, aren&#039;t you?<br />Any suggestions would be welcome so I can go and swot up before committing myself.<br />

At 2 ft. they would just be able to turn in my tank.
If they got any bigger....  :-\
I intend to offload my existing fish to the LFS.
I've been hunting down info. on the web and it seems that the ideal is a 8'x3'x3' tank!

Silver dollars: been there and got the t'shirt . Lovely in a large shoal.
Anway, this thread was in catfish Capers and I don't want to bang on about other fish. Not fair on the rest of you lot ;D.
I'll put on my thinking head (if I can find it) and maybe with some recommendations I'll have some good sized fish to enjoy.

Thanks lilac, nice talking.

Hi Bipolguy and welcome to Fishcrazy! [wave]

The redtail can grow to over 3 feet so you'd need a tank at least 8 x 3 base area. Have you thought about arowana?
