How To Tell If Your Fish Is Blind
The first step is to rule out treatable illnesses by checking for signs of infection parasites etc.
How to tell if your fish is blind. Put only compatible fish species together. Oddly enough i have a tank of blind cave tetras they have no eyes and they don t bump into things. Move some of the obstacles around in his tank.
The eyes may improve slightly with healthy water but unfortunately for this poor fish the damage from toxin exposure is permanent and he will likely be blind for life now. Do not create tubulance he will feel that too. Give your fish enough tank room to live comfortably.
Get something like that that will not disturb the water too much leave your lid up for a while and sneak back up to the tank fish can feel you walk. Since the fish can only sense the pot by sight not by any other means like smell sound and vibration. If he runs into them he s most likely blind.
I had a betta fish once he acted very scared around the other fish and if your other betta is a male too that may be the problem. A good rule of thumb to follow is no more than 1 inch 2 5 cm of fish per gallon. I don t know of any cure for this.
Lastly next time don t buy too many fish at the same time because the good bacteria in the fish tank might not be able to handle it. Yes your fish probably is blind. Slip the object you chose into the water and just in front of the blind fish.
If he can see he will move away from the stick. Do not give up on him. So limit the number of fish in your tank keep the water clean and give your tank time to adjust.
Only then i realised that they were not blind. As for him being blind thats really hard to tell. Fish tanks need time to cycle in order for them to process the extra ammonia created by the new fish.
So if you ve been doing that you ve got a pretty good chance of a fish with an eye problem. You don t want your fish to eat hurt or aggressively compete with each other. I know that some fish go blind when you put black lights on the tank.
Or you might like to place a mirror in your the tank and see if your apisto response to its own reflection. He will adapt to his handicap with time but you will need to make special efforts to assure he gets his fair share of food.
