Treatment of head holes for discus, angelfish and cichlids, 3-day course of treatment
The eSHa HEXAMITA hole-in-the-head treatment cures hole-in-the-head disease in discus, angelfish and other cichlids, as well as gill worms and intestinal disorders. The course lasts 3 days, with 25 drops per 100 litres on the first day, then 12 and 12. A 20 ml bottle treats 800 litres. The formula contains copper, so overdosing must be avoided.
This dropper bottle treats hole-in-the-head disease, which erodes small pits on the forehead and along the lateral line of discus, angelfish and other cichlids. It also acts on gill worms, intestinal problems and excess skin mucus. One 20 ml bottle covers a full course for 800 litres, which is 2 complete courses for a 300-litre tank.
🐟 What the disease causes
The parasite responsible lives in the gut, and most discus and cichlids carry it without ever showing a sign. It becomes a disease when the fish's defences drop, after transport, poor water quality, a poor diet or the arrival of a new fish. The first sign does not appear on the skin: the fish leaves the group and isolates itself. Loss of appetite follows, then a dull eye, darkening colour, sluggish reactions, and sometimes white, stringy faeces. The pits on the forehead and along the lateral line come last, and they do not always appear.
Copper means you have to count the drops
The formula contains copper, which rules out any overdosing and means you must calculate your real volume before the first drop. Remove activated carbon, resins, UV and oxidisers, which absorb the product, and leave the filter running. It is intended for freshwater ornamental fish and excludes animals raised for consumption: in an aquaponic system, the copper would pass into the biofilter and then into the crops, so the treatment is carried out in a hospital tank, never in the loop. A copper test lets you check what remains in the water once the treatment is finished.
🧪 The 3-day course
For 100 litres of your tank, use 25 drops on the first day, then 12 drops on the second day and 12 on the third. The formula contains copper: even for a fish already showing the late signs, this dose must not be exceeded. Feed less during these 3 days: nothing on the first, half a ration on the second, then a gradual return.
Support healing once the treatment course is finished
Once the 3 days are over and the activated carbon is back in place, your fish's lesions slowly close up. The eSHa Optima tonic, made from plant extracts, trace elements and vitamins, is then given every day in the tank water. This tonic does not replace any treatment: it is given after the course, once the copper has been removed by the activated carbon.
A water change is generally not necessary either before or after the course of treatment. It becomes so in three cases: poor-quality water, which you check before the first drop; a regular water change that falls within the 3 days; another treatment given just beforehand, after which you change 40% of the water 2 days running while filtering through activated carbon. Any water removed takes away part of the product, so you add back the dose that corresponds to the volume replaced, never exceeding the recommended dose, since the formula contains copper.
🔬 One treatment for several parasites
The parasite in question, Hexamita, has relatives among the intestinal flagellates, Spironucleus and Octomitus, which the formula also targets. It also acts on gill worms, fin rot, fungal infections, dropsy and other skin parasites such as Ichthyobodo or Cryptobia. When several conditions affect your fish, it is given at full dose alongside the treatment for white spot or the treatment for skin worms, but never with another brand's product. In aquaponics, tilapia are also cichlids, but they are raised to be eaten and the instructions for use exclude them; the tilapia rearing guide gathers together their rearing conditions.
