How many plecos do you have in your 55?
Well, 6 now, its a story how I got them all. I will be letting go of a few because I am SURE this is killing my bioload. Also I am upgrading to a 90 once the stand gets built.
I had a clown pleco, and I was battling some algae, clown plecos are pretty worthless at that and the point I never saw it he became pretty useless to me. I found a couple from a local club that was interested in the clown and was willing to trade me some bristlenose plecos. They breed fish, cichlids mainly but had a ton of juvie albino and brown bristles. She offered me 4 for the trade, I only wanted 2 really a male and a female, but I took what I could get. They were and still are about an inch or less in size, and its hard to sex them this small so hopefully I can grab a pair. When trade day came I ended up with 5. 1 of them was VERY small still, 2 albinos and 3 brown ones.
I just figured I will let them grow out take 2 or 3 that I want and trade the others later. By the way these guys are GREAT for algae even being this small my algae on my décor is pretty much gone, I always kept the glass clean.
Then my mom told me someone her and her boyfriends daughter knows was getting rid of a 10 gallon that had an angelfish in it. I thought GREAT I need another angel for my stocklist in my 90 and what the hay its FREE!! and a free 10 gallon with led hood and a bunch of goodies! Time came to pick up the tank, and guess what the angel died the night before. I did not know about this Pleco being in it, so I took it for the time being and got the tank. Now I find out how bad of shape he is in I have no choice but to try and get him back to looking better.
Honestly though, once hes looking good I will more than likely trade or sell him to someone wanting him.
So yes, this tank has a horrible bioload with 6 plecos, but I only have 1 angel, 5 rasboras, 2 german rams and 3 otos in with them at the moment. Glad I gave away 9 other fish just 2 weeks ago!
