Wonderful, wonderful pictures! How many tanks do you have? I noticed the different types of substrate. Also, are you worried your knife fish will finish off the others in the tank? I know they get quite large! Thanks for the wonderful pics!
I believe you need to research some of those fish as if I remember correctly the knife and fire eel might do some damage and the gourami and african butterfly fish might fight but besides some possible stocking problems (don't wana be mean) nice tank.
The fire eels have been in these tanks for 2 1/2 yrs with no problems.My AFB has been in with gouramies for 2 yrs with nothing more than the odd pushing match. lots of floating plants. The ghostknife is only 5" long and i feed him bloodworms krill and he eats the shrimp pellets. He will be in the 180 gal before hes big enough to be a problem. O AND BY THE WAY MORE PICS. HA HA HA HA
Fishfanatic ... your tank looks AMAZING! I have a terrible weakness for fully planted tanks, lol. Truly beautiful tank, and wonderful angelfish! LOVE everything about your tank By the way: How large is the tank? What plants do you have in there (and how many)? What lighting and substrate? Sorry for so many questions!
