Currently I have a internal filter that's meant for a tank double the size of mine (which puts my mind at ease), but I'd like to run an external at some point.
It's 30 inches. What stocking issues do I have?It's overstocked, IMO. A 25 gallon is 24" long (this is according to my research; correct me if I'm wrong) and that's too small for a BN pleco. You also have other stocking issues if you'd like to discuss it.
Hmm, I read before that 3 is fine but I'll probably get a few more then.If it's 30 inches, then your BN pleco should be fine in there. Stocking issue is that, it's not a good idea to have 3 kuhlI loaches. KuhlI loaches love to be in groups of their own species, so I recommend upping the kuhlI loach numbers to 6.
I did hear about that issue but I only have the one bn so I don't think it'll be an issue.You've got some room for mid-top dwellers, but I would not add anything else to the bottom level other than adding more kuhlis so they'll be happier. It gets crowded down there. I don't know about yours, but I had a couple BNs awhile back and they did well for a long time, but eventually became territorial over their caves and chilling spots.
I'll make sure to keep an eye on my bn in that case. I don't have any intentions of stocking any more bottom dwellers anyways (other than more loaches).I didn't mean just to each other... I mean it started that way, but then they kinda teamed up to hold down prime real estate inside the biggest lava rock and freak out on anyone who came close. It was very subtle, and took a lot of sitting staring at the tank to notice. Lots of people keep them in all sorts of arrangements and they do great, especially singly. I'm definitely not saying yours won't do well, I think he'll do just fine as long as you give him proper care, and maybe even if you don't. What I said was that you really don't have any more room for bottom dwellers other than upping your shoal of kuhlis.
