ANSWER: Hi Patty:  ok... first of all you are going to have to thin that tank down.  You have too many fish and they are getting to the sick.  Healthy fish should fight off Ich, velvet, etc.  Do you clean the gravel????   if not you will need to clean the gravel and the tank.  You need to find a medicne that has Malachinte Green as its active ingrediant.   please keep me posted in your fishes condition... dave

QUESTION: have dave, thanks for the advise. i do clean the gravel with a gravel vac. do you recommend a certain med.? and the to filters doesn't mean you can put more fish in the tank? thanks patty

Answer
Hi Patty:  There are a lot of medicines out there for fish these days... I don't really know the name of just one that has Malachite green as its active ingredient... If you go to an aquarium... not a pet store... you should find one... The other thing that has been bugging me... is the wide variety of fish that you keep... Some are scaleless like the loach and the shark... some like a low pH like the Rams... but the angels should do better with a higher pH 7.0-8.0.  The Rams are fragile so I find it odd that they are ok but the angels are sick... Crank the temp up to about 88 degrees... slowly ... one degree per hour.  Keep an eye on the sharks though... they are not going to like that... I honestly think you are going to have to separate those angelfish from the rest of them.  Let me know what happens... dave
