Yo yo loaches sitting still from time to time
So I added two more yo yo loaches and the one loachthat was lonely and skinny seems a lot more lively now and looks like he gained some weight. From time to time, I'll see one or two of the loaches out of the 5 lying almost lifeless on my heater's suction cups or on one of the ornament pieces. It almost looks like they are dead, but when I click on the glass near them they start moving again. Is this behavior normal? They find a spot and just lay there lifeless and I've seen it quite a few times. I do weekly water changes and just did one Saturday about 35% of the water instead of the usual 25%. All the other fish in there seem to be doing well. I use Seachem Prime for the water conditioner.
I feed them a wide variety of food usually two times a day. Flakes, zucchini, frozen bloodworms, freeze dried bloodworms, peas, shrimp pellets, algae wafers
Here are my specs:
55 gallon aquarium
Two filters (One Aqueon Power Filter rated for 30-45 gallon tanks and One Top Fin Filter for 25 gallon tanks)
One heater running at 80-82 degrees
Do 25% water changes, just did 35% yesterday
Two guppy fry a few weeks old
2 Adult guppy
2 Mickey Mouse Platy
2 Silver Platy
1 Rubberlip Pleco
5 Ghost Shrimp
Resting is normal loach behaviour. Though I would suggest a couple of changes from the info you have provided.
First is temperature. Assuming this is not due to seasonal weather but the heater setting, I would lower it to around 77F. Although a riverine fish, this species (Botia almorhae) inhabits calm water pools of highland streams in India, Nepal and Bangladesh, possibly Pakistan though this is doubtful [I'll explain this below]. Highland streams are generally cooler than lowland rivers.
Second is feeding, I would recommend once a day and then miss a day or two each week (water change day is one that can be missed). Restrict frozen bloodworms to once or at most twice a week. The beggies are good, but "meat" is essential as these are primarily carnivorous. The small snails will eager be eaten most times.
Water changes are important for this species as it does not tolerate poor water quality or nitrates. Not that yours are bad, but a 50% water change weekly would be better.
Now on the Pakistan item, in case you/others are interested; I always like knowing these things about my fish.
The exact species name of this fish is still uncertain. Originally it was deemed to be Botia lohachata, the name assigned by B.L. Chaudhuri in 1912, and it is still widely seen under this name. Botia is derived from an Asian word for soldier or warrior. In the early 1990's it was suggested that this species epithet was a synonym for Botia almorhae, the true species, which had been described in 1831 by J.E. Gray. Dr. Maurice Kottelat (2004), an acknowledged authority on this family, assigned the name B. lohachata as a synonym of B. almorhae and not a distinct species in his major revision of the genus which he separated into seven genera.
Steven Grant (2007) has proposed that B. almorhae may in fact consist of five distinct but closely-related species:
Botia almorhae Gray, 1831
Botia birdi Chaudhuri, 1909
Botia lohachata Chaudhuri 1912
Botia sp. "Kosi", possibly a variant of B. almorhae
Botia sp. "Teesta", possibly a variant of B. almorhae
The striking similarity in pattern among these fish certainly makes this feasible; Dr. Bill Eschmeyer at the California Academy of Sciences--Ichthyology has accepted the validity of the first three distinct species. The authors of Loaches Online accept B. almorhae as the species of the subject fish. The occurrence in Pakistan is restricted to the species B. birdi described by Chaudhuri in 1909.
[Finally, the Pakistan connection.]
You'll want to be a bit more careful of having fry in the tank with your loaches as they get bigger, if you aim to keep them. I've seen them eat lots of fry in my own tank. I've also transferred snails to the tank for them to eat. Meat eaters indeed.
I just wanted to post an update. All the other loaches seem to be thriving, but this one fish the skinniest one, even from the beginning appears sick and just does not thrive at all. He just finds a spot to lay down on and looks completely dead. I did a 50% water change about 2 days ago and all the other fish are thriving as usual but this one loach found a new spot now and he lays down with his belly up. I'm not sure what to do at this point. Please see video link below to see what I'm referring to. (Also, I know the decoration is horrible and that's one area I'm still working on slowly but surely).
Another final update - Looking at it a few times this morning, it seems to be doing OK. I do see it doing these seizure type movements sometimes and I know I've seen it with some of the other loaches in the past. Also, shemauri - You are right about the fry but I think having it in a breeder tank within the same tank as the loaches made them adjust to it. I waited about a month and half before I released them to see how they do and so far about a month later, they are doing fine. What's interesting is that one of the fry is doing better than the other in terms of growth. By that I mean I see coloring on the tail and skin, where as the other fry is finally starting to show changes about a week and half later. I wonder why that is...
