Im Worried About My M8s Stocking

[fiskkeeperpro]

In my m8s 5 foot tank, he has the following:

2 Discus
4 neon tetras
4 harlequin rasboras
1 shark catfish
2 Black ghost knife fish

He is going to get 2 clowns loach, 6 more neons and harlequins, 1 elephant nose fish and 4 more disuc with another shark catfish. Im worried about the knife fish, he says they will be fine and the pet store owner said these fish wil all be ok together but im not sure. So, can you guys comment on this? His filter is a small internal filter suitable for tanks up to 220l aswell.

I think he will need a bigger filter and quick, also, I think shark catfish are also called columbian sharsk, which require brackish and will get too big for even a 5' tank. The BGK may also eat the neons when they get big enough.

Hey, what are the tanks dimensions? a 5 foot tank should surely hold more than 220litres so he will definitely need a bigger/another filter

as stated the shark catfish is brackish, and will also eat the neons and rasboras when big enough so needs to be rehomed.
I would rehome at least one of the BGK's, simply due to their eventual size, then you have the decision whether to keep the 1 BGK or the small neons and rasboras. The BGK will eat the small fish eventually.

Both the clown loach and elephant nose need to be in larger groups and i wouldn't recommend keeping both in the same tank, the elephants are so fragile and the clowns can easily damage them with the spike at the front of their mouths (i found this out first hand a few years ago).

Mormyrids (elephant noses) & Knifefishes don't get along due to both having eletrical fields. It's not just a rumour as I tried it and my knife fish kept lashing out at my mormyrid and causing marks on his skin so I had to seperate them soon after. Some may argue that in a bigger tank they can avoid each other but I still would never reccommend it.

blimey that tank is going to be a disaster zone soon and hardly the ideal environment for discus. He could keep the BGK with the Discus as I did and they got on fine but as already mentioned they love a little tetra for a snack. His tank would look great if he kept a shoal of discus with shoals of tetras and maybe the clowns with it

Agreed, if it were me i'd go for one of the following:

A
Discus
Clown Loach
BGK
a couple of small exotic plecs, (King Tiger would be my choice)

or

B
Discus
Harlequinns
Rummynose Tetras
Black neons
Corydoras

That is going to be one wild tank...that's for sure. I'm certain that the discus won't be happy enough to spawn, that's for sure. In short...it MIGHT work, but I wouldn't do it. LOL

i gotta say please no on him getting the clowns

 

[fiskkeeperpro]

he has just got a 12 inch plec that keeps excreting stuff everywhere and still has no external filter. After christmas he is going to spend £110 on 2 dicus.
He don't listen to me.
