Oodinium & Cryplocarion

[jhnrb]

Oodinium (coral fish disease) - The effect of the parasite manifests itself by destroying gill tissue. other affected organs are not damaged. Oodinium enters the epithelial tissue of the gills, forming visible white knots on the gill tissue. severe cases lead to respiratory problems and end in death. OBSERVE THE RESPIRATION RATE OF THE FISH. IF THEY RESPIRE FASTER THAN YOU CAN COUNT, THERE IS A PROBLEM STEMMING FROM DAMAGED GILLS (LACK OF OXYGEN) OR, LOW PH. Treatment - Copper Sulfate (0.8 to 1 mg/l) this medication is totally unsuitable for invertebrates, and it disrupts the biological equilibrium of the aquarium, therefore, it should only be administered in quarantine tanks that can be totally cleaned afterwards. MarinOomed (tetra) is significantly milder and safe for invertebrates.

Cryplocarion (Marine Ich) - Cyptocarion tomites attack the fishes by attaching to the skin, however, these are significantly larger than Oodinium tomites and therefore, easier to see. Treatment - 1) prepare high quality sea salt for a partial water exchange, airate 24 hrs. 2) Remove 1/2 of the tank water and discard 3) The new seawater (or well matured water of a lesser quality brand of salt) is placed into the tank until it is 3/4 full 4) top-up the aquarium with freshwater (tap,water or water processed through ro system) that is free/low in nitrate until the aquarium water has a specific gravity of 1.017 to 1.018. 5) add Tetra MarinOomed. Lowering the salinity is usually safe for invertebrates, only crustacea such as shrimp and lobsters are sensitive.

Cryptocarion is always latent in an aquarium (and on fish). The outbreak occurs "overnight" under stressful conditions, e.g, when the Ph falls below 7.5. If the water quality problem is corrected, the disease usually disappears without further treatment.
