Let me explain, on this forum you might have seen me say I want a fahaka and a palembang. Well the fahaka can't happen because I live in a flat on the 4th floor

the reason why is because I was paranoid that the tank will be far to heavy for the floor and a disaster would happen, potentially killing someone. (Prisoner) "So what did you get locked up for?" (Me) "For killing someone with a fish tank" lol. And the palembang, well its a lovely looking fish and its like the next step down from a fahaka but I'm put off because it's a lurker and doesn't really do anything all day but sit and wait for food. The tank will be in my living room and its my biggest tank 200l\44g so obviously I want it to be entertaining and also with the palembang there's a real chance of me getting bored, so I've decided I'm not taking that risk. Marine and brackish aren't an option since i don't want to faff around with mixing the saltwater. So I think it could well be 1 or maybe 3 SAP's as my first puffer. Ideally I wouldn't want anymore than that because I'm worried about me not being able to provide enough snails for them to munch on and file down there teeth, I've read they need them daily so that means I need to be able to pump a lot of them out. The tank I'll use for the snails will be a 100l so I'm not sure if that's ok for 3 SAP's?
Anyway on to the actual tank mates I would like.
Ctenopoma acutirostre x2
T bar cichlid x1
Purple Spotted Gudgeon x1
I know there is a sticky thread basicly saying I shouldn't bother and only do a species tank but if you go really far back through the pages you see a few threads regarding this topic. Let me know what you think.
Cheers.
