Ranitidine is a competitive, reversible inhibitor of the action of histamine at the histamine H2-receptors, including receptors on the gastric cells. Ranitidine does not lower serum Ca++ in hypercalcemic states. Ranitidine is not an anticholinergic agent.

What Do Blue Rams Eat? in the Ram Cichlid forums, part of the American Cichlids category.I have a blue ram I got 3 days ago and he despises flake food.ebruary 7th, 2010, 09:59 PM. I have also purchased 2 blue rams 3 days ago. They do not go all the way to the top of the tank. They both swim up the side of the tank near the top then swim back down. The only way for them to eat tropical fish flakes is for me to sink rather large flakes to the bottom of the tank.
