In next year I will bild a new playwood tank.
size 350-400cm long x 100cm x 90cm high.

I bought a few days ago 10xch. pleuro ( 6cm) , and 5 ch.marulia (6cm)

How many and witch SH could I keep in this tank?

pleuro with marulia - could it work?
 
ok, , but how many fish could I keep in this?
 
your marulia depending on location will out grow that tank if they reach there potential , you are limited by the width any tank sould be at the bare minimum a few inches bigger than the lenght of the fish. marulia have the potential of exceeding 100cm in length.

and the pleuro marulia together is a really poor choice , MOST marulia are like micros become aggresive with age , there are exceptions but 9/10 they will not live happy with other fish when adult esp other snakeheads

now , the tank you are preposing is big and if you do your homework and choose a varient of marulia that is one of the smaller varients or maruloids then you could keep a fair few of either , but not noth together.

the problem is marulia are likely to pair up in that tank so no matter how many you put in ,you will end up with only two.

pleuros on the other hand would work fine , as they are a pack hunter and hang around in groups. in your suggested tank you could fit a shelf at the back last foot or so, and plant in heavy with vallis , when pleuros pair up they break away from the pack and go and spawn in the shallow reed beds. then later rejoin the pack . so if you want a load of fish pleuro is the wiy forward

iam not certain on full amount of fish but i would start out with around 20 pleuros and then adjust the level by how it looks as they grow, just growing out pleuros to a large size can be very lucrative ,you would have no problems getting rid of any spare latter on , but you would have great trouble finding adult fish to add if you did not have enough

pullTanks, tropheus thanks for advice. I think it will be pleuros becouse they are more active than marulia.
The problem is I bought all pleuro in the shop. In poland generaly buying channa is almost imposible.

I have also 1 female pleuro about 20cm long, but they dive in other tank in my work.
BTW they doesn't eat for about 2 mounths , and i put in two tilapia. Since that time the chase those fish , and start eat. Unfortunatly they growing slow :(

mayby i shoud put pleuto in to 600l tank with my aurianti(40cm), but I'm afraid that aurianti kill pleuro:(

I like when pleuros hang around in group. Tropeus it is posible that one pleuro in tank grow slow, and group in other tank grow fast?
 
I agree with tropheus, mixing marulia with pleuros will end up most likely with dead pleuros. I would just keep a group of pleuros alone with themselves.

mayby i shoud put pleuto in to 600l tank with my aurianti(40cm), but I'm afraid that aurianti kill pleuro:(

IMO, I would reconsider the thought of mixing the two... it would definitely cause much more problems for your pleuro, especially if already having a difficult time getting it to feed. I would suggest focusing more on your pleuro's health... beginning with it's diet and appetite.

Good luck and enjoy! :)​
 
Hi, I think your best solution is to keep one species of the medium size,of your choice there are many to choose from.

yes mate very possable, it is possable even if they where in the same tank, some fish will always feed well ,be first to the food ect , and grow fast , you will always get the odd one that doesnt eat much ,is far slower and grows slower.

in pleuros this problem is exagerated ,because when kept in a group when one pleuro goes to attack or eat something this automaticly triggers the other to follow it and either attack or eat , a lone pleuro thats a bit slow does not have that automatic trigger.

i know how you feel with no being able to find any in lfs , i searched for many years to get my latest batch, there must of been a decent amount at the indian wholesalers as we have been told more can be orders from india if needed , so may be worth while asking your lfs if he can check the order lists to see if there is any more.

as phull said , pleuro and auranti is more than likely going to be more problematic than its worth , i would just wait until your new pleuros are somewhere near the size of your slow grower and then add him to the pack , he will probably start growing much quicker when he has other fish to take a lead from

I think the suggestion of the shelf being heavily planted is a fantastic idea it will give them space to breed,

an 1 fish growing larger than the others is easily possible, my channa's are doing something similar atm
