The tank is 5 months old, it cycled for 1 and now I am slowly stocking it (check the profile for details!) with all sorts of fish. I was going to do an Argentina biotope but then I thought that maybe bringing all sorts of life into the tank would do it more good.
Did I have anything...
Maybe you should rehome the tetra so he gets a school
The shark will outgrow the tank quite fast so I suggest upgrading or rehoming him, too. Did the other 13 kill each other? They are very territorially aggressive.
Move the convicts to the 29 gallon, but it won't be a permanent home will it...
Yes, they are fin and plant nibblers, but they don't eat a TON of plants.
Cherry barbs also do that, except they don't really eat fins as much.
EDIT: DO you know what I mean? They eat plant material but they won't gobble down every ingle inch of every single plant.
