Today I decided to swap out my 5 gallon hex for a 5.5 gallon AGA. I'm using a base of mature eco-complete topped with inert fine gravel for substrate. I'm using a 27W full-spectrum desk lamp, dosing EI, CO2, and daily excel (small doses of course:smile: ) I'm still not positive what direction I'm going with this, but I'm leaning towards a dwarf puffer. I've already got about 100 snails left over from the hex, so he'll have plenty to eat. I'm not positive about the DP though. Can anyone recommend any "nano fish" from their own experiences? Input, suggestions and comments are MUCH appreciated. Thanks for looking!
