I did have a ProClear 300 wet/dry (rated for 300 gallons) plus Eheim 2028 on this tank. But I kept losing fry to the sump. Not to mention how loud the darn thing was. I now have (2) Eheim 2028's and (2) Aqua Clear 110's. I also have 2 Maxi-jet 1200 power heads to help circulate the water.
No they don't....exactly opposite dietary requirements!
Frontosa are calm, stationary fish, the tropheus are polar opposites, and will drive the Fronts crazy....Tropheus none stop, everywhere swimmers/chasers.....most energetic african fish, bar none!
