The silver dollar is another schooling fish. How big is it and what variety? The larger silver dollars are probably too big for the tank. They are also much like angelfish, rather easy going but if it can fit in their mouth's they'll eat it. If you want to plant the tank I'd definitely take it back, otherwise I think real hard about taking it back.
Hmm...when researching the silver dollar, I came across several types but don't know how to ID him. I took a pic of him today to help you guys ID him, but can't find the adapter to connect the camera to the laptop, LOL, so I'll post it later tonight. It's been in the tank for several years and isn't too huge, several inches across, if that helps.
The loach has also been in the tank for over a year and he's maybe 5 inches? I'm not sure. I'm not good at the visually measuring part. I may have a pic of him as well. I'll see. Are they slow growers? Is this guy stunted from poor water quality?

Unfortunately, lots of times they've just topped off the evaporated water and not performed partial water changes. I've found a manual online for the filter (Fluval 304) and I'm going to investigate what media they've been using. I'm not familiar with this filter, so I may be posting for more help in the equipment section soon!
My plan is for ME to learn how to operate the filter and to give the tank a good going over (over the next few weeks, don't want to disrupt too much of the good biobuggies at one time) and then to help them come up with a plan to properly maintain it BEFORE any new fishies get added. The current residents have acclimated, thankfully, so there's no where for them to go but up.
I love the idea of hardy schooling fish that swim in all the levels.
The are several obstacles: no close water supply, who can maintain during the school year and over the summer. The school doesn't close close over the summer. Also to be considered is that the current fishies have been donated by parents and we need to address the rehoming with them diplomatically before making any changes, etc.. Oh yeah, and BUDGET!!!!!
I probably won't pursue the idea of planting the tank at this time. I think it will make it even more beautiful but is too much to handle right now.
Thanks for all the responses so far. I love this site!
