He swims into walls, corners, he did not react to the net, or a cup, or to another male betta (placed in a bowl and placed into the tank, rim well above water line) in fact he ran into the bowl... His eyes have purple like his fins, then red, then the black pupil. He reacts a little to light.
The tank he is in is what I believe to be a 1.5 gallon tank, soon to have heater. I have a few questions.
1. Feeding is not a problem, although he is much slower. Because he does not eat everything before it sinks (3-4 flakes) how many should we feed him? We also occassionally give bloodworms.
Right now he is in a small tank, by himself. The tank size I reckon is 1.5 if anything - yes we will upgrade as needed. There is a heater, and she is dedicated to cleaning the tank properly (which is today, where I can show her how - I have many fish and betta :) ), so not too worried about a filter yet.
2. Because he is blind, would a filter bother him much? I have found ones made for bowls and tanks - so I guess it would be small enough. I am pretty sure that one is a bubbler.
3. What size of tank should he stay in? I do have a 3 gallon 360 view tank with bubbler. He seems to just follow/bump the sides of his tank and sleep on the top.
4, Are there really any problems people have had with blind bettas? Remember, his is genetic, and he is completely healthy and active.
He is very healthy otherwise, so we determined its genetic (all well).
