hi, are bala sharks completely peaceful fish and will they be fine with guppies, also, will it be alright to have 1 bala shark in a 240 litre tank with 8 guppies, 6 black widows and 6 corries.
bala sharks are schooling fish and should be kept in a group of at least 5.
they will reach 18" as adults and should not be kept in any tank less than 4ft long, 2ft wide.
