I didn't expect them to grow so fast! I do want a bigger tank and was thinking that in a few YEARS, but the pleco has grown alot. When I first got the tank, I got 6 little fancy guppies to cycle the tank. They did great. After a few weeks, I went to the store with my kids and asked for help in populating the tank the rest of the way. I knew I wanted a pleco and wanted my kids to each pick out something. One got two tiny angles, one got five little neons and I got a little Pleco. The guy at the store said that in a few years, I might need to separate the neons and the angels but that they would be fine for now.
In june, my tank population dropped quickly - the guppies and the tetras decreased dramitically in a few weeks. I called the fish store and the guys were like "well, how big are your angels now, like an inch and half? When I told them how big they were and how big the Pleco was, they were surprised at how fast they all grew.
(does that mean I'm doing a good job taking care of them? does it mean that they didn't know what they were selling me? I was pretty clear about what I had.)
I got the little tank for the tetras - it was dumb, but my son was upset that "Anchovy and the crew" were getting eaten and didn't know that I had to buy 4 new tetras because only ONE was left by then.
I got some tiger barbs and a red tailed shark. The barbs didn't make it, but the "shark" is doing well.
So, yes, no, I don't know if its temporary. I didn't think they would get this big, but I only have the pleco, the angels, the shark (which is small) and that one lonely guppy in the 20 gallon. Does that seem like alot? I thought I knew what I was doing at first, but now, I feel like a dumb noob since I'm realizing I don't even know how fast they were suposed to grow.
