hi ihave a 350 litre corner tank currently housing 2 severums 4" each ipink severum 4 " jewel 4" and i tiny plec.

hi thanks for all the info, as i described in my original post my fish are all tiny in comparison to the tank i mean its got to the point people are asking me why i have an empty tank !!!
so i wanted these fish at their adult size however as usual financial rasons meant that i had to have them from babies.
the man in the
LFS assured me that they would grow rapidly so i have had them for 1 month and im not expecting miracles but they havent grown at all. i am doing 2 weekly 25 % water changes as there small at the moment and feeding them good quality flake and cucumber and blood worm.
the problem is that they are refusing the blood worm so i bought hikari mini pellets for them the ones for the growth and the ones for the colours but as there used to the flake falling to them ... they arent interested and there simply getting sucked int the filter..
help...i feel like going out and buying a tiger shovel nose!!!!! at least they grow rapidly!! (joke!!)
but it really is frustrating..
i suppose now even if i saved up for a adult it may eat the smaller fish?
please advise...
