Will These 4 Plecs Be Ok In My Tank?

[Neal]

Ok, I have a 20Gal UK tank, and today I went out with my dad and bought 2 BN plecs, but what I never knew is my mam also went (parents have split up and tanks at mams house (my house)), and she bought 2 pitbull plecs, would these be ok in my 20G tank? It is over filtered with a fluval 2 running and a brand new fluval 3+ set at highest pressure but facing towards back to stop a very high current.
I know plecos are very messy animals but I can keep ontop of water changes.

I think your tank may be too small for all 4. BNs grow to about 5-6", and Pitbull Plecs are smaller (2"), but even so 20g is probably too small.

Even if it's overfiltered and I keep ontop of water changes? It will have plenty of caves so I doubt there will be aggresion or anything and plants, they are all only very small now, so you never know by the time they are adults I might have a new tank, but I think that would be a deffinate no-no! If they show signs of being uncomfortable or anything when they are adults, i'm positive my LFS will take them in.

I think that all 4 may be pushing the limit, plecs are real poop machines. You may be able to keep up with the tank maintainance short term, but it will eventually become a chore. My advice would be to keep one BN or 2 Pitbulls but not all 4.

if you do keep ontop of water chnges and filter maintenance, you will be find

we used to breed BN's in a 15us... a big filter and a lot of water changes and they were fine

It's a 20 UK, so it's quite a bit bigger than a 15 US. A fluval 3 is more than enough for a tank of that size, it's for something like up to 130L, and I do water changes every Sunday, or if I see my fish acting strangely.
Thanks,

thats 90L so nearly twice the size

make sure you have some nice hiding places.

The pitbulls will not really bother but the bristlenoses will like a cave

I'm planning on coconut caves covered in some type of moss, maybe making 3 or 4.
