Options to replace a BN pleco

[Catfish586]

I'll be honest a 100L ~25 gallon is pretty small for either pleco or cory much less both. If you do go with cory i would go with pygmy or hastatus. The behavior of these are atypical of most cory but they are also 1/4 the size.

If we do get another BN (with or without corys) it will be a little one with a view of upgrading to a larger tank when it gets too big for 100L, but yes, tank size is a major consideration. We upgraded to 100L last summer for the BN's benefit but I soon realised it was still a bit on the smaller side for a fully grown adult BN.
