TL;DR: Filtering a 65g tank, HOB or canister? Heavily Planted with shrimp and angels? Maybe discus? I'm on a small to moderate budget. What are your ideas?
I bought a used 65g (dim: 36x18x25) that came with the stand and both lids. The pic is just a representation of the new kits Petsmart offers, but is the same setup I bought. I got the the whole thing for $100. I've read that some owners have had issues with this tank holding its water and busting a seam. The previous owner had it for 6 months and claimed that it held water just fine. I will be doing a leak test outside to make sure there are no leaks from moving it. After I clean it I will post pics of some areas of the seams that I would like a second opinion on, just to be sure.
For now let's assume it will hold water like a champ. I plan on moving my planted 29 over to the 65. I have an Aqua Clear 50 HOB that I really like so I was considering upgrading to an AC 70 or 110, but perhaps a canister would be better. I know almost nothing about canister operation/maintenance though. I could also do a basic DIY canister using PVC pipe, just not sure what kind of pump to use. I have an adult male angelfish who can be quite aggressive, but I might sell him in favor of getting a few juvenile angels instead. He came with the 29 and I hate to see him go, but he doesn't play well with new fish. I was also considering discus instead of angels, or maybe just many smaller fish in a heavily planted tank. I like the angels but I also want a lot of plants/hardscape and some shrimp too. Not sure if shrimp and angels would work out though, even with plenty of hiding spots. My budget is small to moderate but I'm good at DIY, so I can get a lot done on a tight budget.
What are your thoughts and advice? Thanks.
